Gillispie, I normally only play 2-3 zone. When playing outside shooting teams I would play +2 or +3. That would be the same thing as +0, +1 in m2m?
Also how does small forward play change when switching from 2-3 to 3-2? I would also assume you will get more rebounds in a 2-3. Thanks again for any info. I have made it to the s16 running zone but I have honestly been off that +2 most of the time which would have made a difference in a few close games.
edit: sorry this is so long, but the "what is the difference in 2-3 vs 3-2 with respect to SF" question is like, one of the hardest and messiest questions you can ask/answer in the entire game. it took me more than 5 years to have ANY answer. maybe in another 5 years ill have an answer that is moderately concise, but really, its a messy issue and i see no way around that. i know that i didn't do very well answering, but i did my best, hopefully its worth something to somebody...
yeah, i mean its not exactly the same thing, 2-3 +2/+3 as m2m +0/+1, but i think its a good way to start thinking about it. if you really want to get into zone, it would be good to study the impact of 2-3 and 3-2 + and -, not only in terms of 3 point defense in the general sense, but also splitting into the two components of 3pt defense - 3pta allowed (3 point attempts allowed) and 3pt% allowed. i am definitely not a zone master, but if i was a zone master, i expect i would be able to explain defense in terms of those two components, not just overall 3 point defense. my take is the 2-3 allows more 3 point attempts, so like a 2-3 +2 would probably allow more 3 point attempts than a man +0, but the 3pt % would probably be about the same. but i never was able to fully figure that out.
regarding the rest of your question, the 2-3 vs 3-2 difference in terms of the small forward is this. when you run a 2-3, the players are grouped together - by the defensive equations they use. its not intuitively obvious what that means, but its probably the most misunderstood thing about zone, so i just want to emphasize it (its so misunderstood because the way it was explained by admins was confusing, for years and years - i only just realized this when i ticketed seble myself less than 2 years ago!). anyway, if you have a 2-3, the pg/sg share an equation, the sf/pf share an equation, and the c has their own equation. then, in defending a shot, ALL FIVE players are averaged together, their defensive abilities. advanced note: the equations of each player also depends on distance from the basket. in a 3-2, the pg/sg/sf all run off the same equation, while the pf/c run off the same equation.
i might be overly redundant here but im still not convinced that is clear, so here is a quick example, and ill carry it through to how a sf is impacted. when its said that the defensive equation used is the same, its talking about the defense equation that weighs ratings and IQ and comes up with a "defensive goodness" for a player. so, lets suppose a guy is taking a shot from 18 feet. then, in a 2-3, you might have:
pg/sg equation: def ability = 5 ath + 7 spd + 10 def + iq
sf/pf equation: def ability = 8 ath + 5 spd + 10 def + 5 sb + iq
c equation: def ability = 8 ath + 3 spd + 10 def + 9 sb + iq
then, your pg/sg would be evaluated based on the first equation (which is obviously over-simplified, but hopefully you get the idea). your sf/pf would be evaluated on the second equation, and the c would be evaluated on the 3rd. all 5 values would be averaged together, and then this is your defensive score for defending the shot in question (the shot from 18 feet).
in a 3-2, you might have:
pg/sg/sf equation: def ability = 5 ath + 7 spd + 10 def + 1 sb + iq
pf/c equation : def ability = 8 ath + 4 spd + 10 def + 8 sb + iq
then, your pg/sg/sf get evaluated by the first equation, and the pf/c get evaluated by the second. then, all 5 are averaged together, and that is your score.
so, what does this mean? well, first one high level comment, which hopefully helps make the above make a bit more sense, in context. some people have talked about using zone to "hide a defender". well, all 5 players average together on every shot, so you can hide one in the sense that the opponent cannot point a 20 ppg player at your ****** defender and let him run wild. but, your crappy player is still important on every shot. also, some people have said things like, well, my pg is my bad defender who i need to hide - so i need to play 3-2, so hes averaged with 2 other players, instead of just 1. i don't think it really works that way, its not that the pg/sg are averaged in 2-3 and pg/sg/sf in the 3-2, all 5 players are always averaged together, its just that those groups of players are evaluated off the same underlying equation.
so, when you look at a 2-3 vs 3-2, what that really impacts is how your team is going to play, defensively. there is a rebounding component - a 2-3 is slightly better than a 3-2, although because you usually play a 3-2 at a more negative setting than you'd play the 2-3, i think defense is really the focus. there is no impact on offense or turnovers, as best i can tell. the first defensive issue is defending 2s vs 3s, like we've already talked about - that is an opponent specific decision.
the second aspect of the defensive tradeoff in the 2-3 vs 3-2, is a YOUR TEAM specific issue - its not about the other team. we don't know exactly what those defensive equations look like, for the different players. but, we can safely assume, the per defense equation used in both the 2-3 and the 3-2 (which may or may not be the same - but at least, its probably pretty damn close, right?), its about per defense - speed will matter more, sb less, than in an interior defense equation. so, if you are playing a center at sf, who has 99 ath/def/sb, and 1 speed, then having speed be critical in their defensive equation, while shot blocking is either not a factor or is a small factor, well that probably isn't so hot for you. similarly, if your sf is a pure guard, who has 99 speed and 1 sb, then having them evaluated in the 3-2, where sb is a slight or non factor, is probably a lot better than having them evaluated as a sf/pf in the 2-3, which is most likely a hybrid equation half way between per defense and what you'd think of as a center's defensive equation.
i hope this is making some sense, because its fairly difficult for me to explain and i am trying, but i know its a tough subject... feel free to follow up with questions, or to let me know straight up where i am totally rambling and what is making sense, and ill try to clean it up.
anyway, when i look at my team only (my opponent-agnostic, base team setup), i usually do try to decide if 2-3 or 3-2 fits my team better, and primarily, that comes down to my sf, as i explained above. i am assuming, in a 2-3 and 3-2, the per defense equations are roughly equal, so my pg/sg are using the per defense equation no matter what. however, the pf and c are also using different equations, in the two sets. in a 2-3, your sf is running on a sf/pf equation (wing equation, if you will, if you think about 5 guys actually playing a 2-3 zone, where they start out standing), your pf is running on a sf/pf equation, and your c is running on a center equation. in the 3-2, your sf runs on a per defense equation, your pf and c run on a pf/c equation, which i suspect is like, half way between the sf/pf and c equations in the 2-3?
sb matters significantly in the zone, and i think the major tradeoffs between the defensive equations, mostly come down to spd and sb, but also ath to some extent. meaning, defense matters a ton in all equations, but spd matters mostly in per defense, while sb matters mostly in inside defense. ath probably matters slightly more inside defense than on the per, but probably not by a ton. so, if i've got a pf, who is a center type, sitting there with 95 ath/sb and crap speed, i would rather him play in a 3-2 as a pf/c equation, than have him play in a 2-3 in a sf/pf wing defense type equation. i suspect the pf/c equation in a 3-2 is more like the c equation in the 2-3 than the sf/pf equation, because its really a paint defense role more than a wing defense, but i can't back this up from experience, its only what i would assume logically, which is a dangerous thing to do in this game ;) at least, its dangerous to put too much stock in it.
so, just to pull it together, if:
- my small forward is very guard-y, i am more likely for my base set to be a 3-2, probably like a 3-2 -2 or something.
- my small forward is very big-y, i am more likely for my base set to be a 2-3, probably like a 2-3 0 or something (generally when i play a 2-3, i know i am giving up 3 point defense, and gaining on the boards and for 2pt defense, the goal isn't to have your 2-3 base and your 3-2 base be the same, just for both of them to be solid)
- my power forward has poor sb and better speed, i am more likely to play a 3-2
- my power forward has great sb and poor speed, i am more likely to play a 2-3.
i've definitely had teams where i had extra players (as zone teams often do), where i would run different lineups, a smaller lineup playing 3-2 against great 3 point shooting teams, and a bigger lineup running 2-3 against poor 3 point teams, and i found that to work fairly well.
ok, ill hang up for now... but to any zone coaches out there, please don't be overwhelmed by the length and give up on it! 2-3 vs 3-2 is somewhat of an eternal mystery in HD, and i certainly haven't totally cracked the code, but i think i have the core laid out here, and i think all competitive zone coaches should really take the time to try to understand it... its too important to making zone work-able. zone gets a bad wrap, but its not a bad set. if you can understand and work with the info here in this post, and also embrace the core value of zone, which is allowing you to really focus on signing star power players, and being able to play them for more minutes, while being able to skimp on depth and take more risks in recruiting - then you can really put together a fine zone program!
edit: final advanced note (feel free to skip) - i never was able to figure out the implications of, "the defensive equations depend on distance from the basket". i mean, what it clearly means is, that for say, a center, when he is guarding a shot at 2 feet, its going to be a pure big man type equation, his speed may literally matter 0% on that. but for a 10 foot shot, the centers speed in trying to be a factor in that play, might matter. or something like that. but is this all there is to it? is it just more of the same - the per guys have per equations, which rely more on per def stats (spd) when its a true per shot, and that sb actually matters some for those folks on shots in the paint, even though they might not be anywhere near the basket? or is maybe the distance from the basket being used as a weight, of sorts? on a 3 point shot, it doesn't exactly make sense for a center to weigh equally with the other 4 - maybe the distance from the basket is used so that the guards count as a full weight, the wigs as 75% weight, and the center as 50% weight? or something conceptually similar to that? i don't know. i never could figure that out, or get a straight answer out of seble - although im not at all convinced i was able to ask the question in a way that makes any sense. nor am i convinced the question make sense here. but i think it would be worth someone, who was winning titles with zone, trying to be the best zone coach ever, to pursue this issue further. at stake, is the question - if you play guards with sb, how much impact does that have against a shot in the paint, by a post player? if we are to belive all 5 guys are averaged equally, and the distance factor in the equation for the guard serves to make sb more of a factor, then maybe the sb of a guard does actually matter - but not in defending guards persay - rather, in defending shots in the paint! regardless of who takes that shot.... i don't know, its interesting. i wonder if the other defenses use distance in their defense equations, as well? i think ill ticket and ask that - if all sets use distances in their equations - then those equations are probably more about making spd matter more no matter who the defender is, when they defend a 20 foot shot, that kind of thing. but if only zone uses distance in the defense equations, then it might be more about weighing the players, to better control how all 5 players defend every shot? ok, im pretty sure im making zero sense at this point. cya :)
