defensively, your team is kind of weak, and thats the most important thing in my book. your team ath/def itself isnt bad but thats not really the point. its not like they are terrible or anything, but in your position id be shooting at least to expect a NT bid. with that level of expectations, i feel like overall your defense could use some work. none of your bigs are strong defensively (at this point in time, at least), and your guards are all weak except morgan, who is solid but not great. rothman is pretty solid but still, thats definitely lower than i'd want them to be, trying to make the NT.
offensively, its an interesting situation. you play a weak schedule so guys with better lp/per and lower ath/spd are able to compete, which is not generally the case in bigger conferences. not one player on the team is a true scorer, but because of the weak schedule, you actually have a couple guys who are pretty good. so i guess thats alright but i personally cant stand teams who are especially effective against weak teams at the cost of being effective against similarly talented teams. the average bottom half NT team is good enough that your offense would really struggle. playing mostly sims, you don't really see it. i had disagreed with that guy in the other forum about it being a bad strategy to shoot to just make the NT, and from there, to work to build up. thats what people usually do from lower prestige, you sort of have to in this day and age. but once you have prestige up to your level, i do agree with him, you don't want to just be trying to romp on sims. i mean, its fine, but you want to give yourself a good shot at a 2nd round and such so you can get a good BCS job, or if you want to stay, so you can get prestige up. its hard to say your offense is bad when you have that stat line, but against good competition, it definitely is a significant weakness of your team. theres no strong spd/per combo guards or anything similar who i would have any confidence in as a lead scorer on my own teams.
final point on offense, i just made this point in a different thread a few days ago. one of the biggest difficulties for NT teams is translating success against weaker opponents into a strategy against stronger opponents. its kind of dangerous to your growth as a coach to rely on offensive guys like knight, morgan, and martz, to the tune of 15ppg, when those guys can't perform like that when you step foot in a BCS conference. the real thing is, as long as you recognize those guys dont cut it against strong defenses, and if you make it to the BCS, you need more traditional scorers who have strong ath/spd (as applicable) AND other scoring ratings to go with it, then you are probably ok. its just bad if you walk away from this experience expecting guys like that not to get killed in BCS conference type play.
also, rebounding wise, definitely feel like you have a need for some more strength in your bigs. i think you can build a significantly stronger rebounding team on that prestige.
the thing is this - your players are like, a lot of them are decent at a lot of things. that is sort of ok in less competitive areas but its really not the right way to build successful teams, its why your struggling to make the NT on a 735 overall, which in a mid major, is a pretty high rating (you should make the NT with that). the trick to this game is having guys who are more slanted. a guy like francis, his 94 lp is basically useless because he isnt very strong offensively. im sure you could have found a 20 lp big who was better defensively and on the boards. the key is to take guys who have clear strengths and acceptable weaknesses, and combine them strategically. so many of these guys are decent in so many ways, its really holding you back. an equal amount of talent could be much more effective for you, and further, i think you are passing on more talented players who are available to you, to get these well rounded type of guys. being well rounded is really not a good thing unless they are well rounded in the sense that they are amazing at everything :)
how far out do you scout? you might need to scout further, consider more recruits. you can regularly find 70 ath/90 reb/90 def type bigs on a C+. a couple of those guys would really go a long way for you (in fact, thats basically my minimum standard for a big at any d1 school - i mean, you can go below in a given rating, like 70 ath 95 reb 85 def is fine). think about this. its pretty common for me to sign a big on a mid major who is like, 78 ath, 96 reb, 88 def, decent shot blocking, and **** all elsewhere. say he is literally 1 in all other ratings (but work ethic and stamina). what do those weaknesses cost him? the answer is very, very little. hes a great ath/def type big for d1 and hes way better than a 68 ath, 86 reb, 78 def guy, with the same sb, who has 50 each in spd, lp, per, bh, pass. thats a 220 point difference and the lower rated guy is better. you mentioned somewhere about wondering if having low bh/pass would hurt your pf, and no, it wont. you can safely sign bigs who have nothing anywhere except ath/reb/def and sb if you play zone (better to have at least decent sb in all sets). none of those other ratings stop your bigs from being quality defenders or quality rebounders. what else do you need from your bigs? nothing. offense can be nice but only so many players on the team need to be scorers.
one thing that i find interesting, now that i think about it, is your comment about game planning... most likely, im assuming this means you are losing the big games you expect to win. its most likely what i described - the quality of your offense is much lower against better teams, and i dont just mean in the general way where all teams scoring goes down against better defenses. your players offense specifically is the kind that works against bad teams and does not against good teams. it almost guarantees you are going to be the underdog in your big games.
