i agree completely on that last note. that is really the problem - not enough penalty for taking such a high % of shots. and to the people who asked if its worth doing with other quality options - that remains to be determined, i'd say. when bing ran it, he could have had other guys take shots, but he didn't. and his two central teams were totally dominant. but how do you know if the team could have been even better? its tough to say, i mean, how much better can you get?
my triangle program at SIUE has been running a similar system for 20 seasons (similar to themselves, not to bingball). the biggest change was back before bing even won a title, we were in a conference in rupp, and i had a vastly better (10 senior) team who he beat a couple times in the same season. i mean his top 2 could compete with my top 10 but by no means did he have the best player on the court. so, i changed my strategy, to lean more heavily on my better players, and it made all the difference in the world (after losing 2/3 in the regular season, we beat him in the final 4 by more than 20). but, i have definitely seen you can push it too far. at least with triangle at my d2 team. when i lean on a guy too hard, my team performance suffers. is flex different? i don't know, but i went from 2 motion and 2 triangle teams to 1 triangle and 3 flex to try to figure it out. my sentiment is division makes a big difference. in d1 defense is just too good, i seemed to struggle a lot trying to give a guy a bunch of distro (i didnt try giving a guy 100% for his lineup, though). in d2, i struggle with it too. i give a guy a whole bunch and find myself curbing it back to increase overall performance. but, the d3 team i tried it with, seemed more feasible. they ended up winning a championship (not playing bing ball, but with 4 guards taking almost all the shots instead of 2, because i had the depth in quality), but tark d3 was so derailed it really doesn't mean much. i think i had like 3 title game appearances in 5 seasons running a similar strategy, so it was definitely successful, though. anyway, that is pretty much the extent of my research into bingball, which is probably as extensive as anybody except bing himself, as i became fascinated with it before he even made his first final 4 (i think).
i think he eventually quit because its so ridiculous how successful he was with such a ridiculous strategy. i personally feel WIS should make a change for guys taking over 30% of the shots or something like that. but, keep in mind bing was only successful in d3. he came to my d2 conf, took a not top 10 team to #2 rpi, but didn't really have a chance of beating my well-rounded team. he didn't stick around long enough to show what he could do on an a+ prestige but extrapolating the results, i was pretty confident he would never be able to build a better d2 program with that style than the more moderate style i relied on.
i think its worthwhile for everybody to experiment with bingball a bit. most coaches probably rely too little on their better players, like i did. don't get me wrong, you can still be successful. i was going for my 4th title in not very many total seasons when i saw what bing was doing. but i never would have gotten to 2 and 3 at a time if i just stuck with the same formula. i doubt i will ever play anything close to true bingball, but it has definitely shaped the way i approach the game today.
edit: i think its worth mentioning that d3 team, i never gave a crap about. i just liked the conference. i say that because i don't want people to compare their success to bing's and say running with 4 guards was less successful, or that if i really understood bingball, they would have done better. i personally think it would have been more successful with the 4 guards than 2. i just don't have it in me to try with all my teams, and i've always been that way. but, that kind of helps the experiment. it meant i was trying with flex teams that weren't that good, if i had the best team in the country, it wouldn't really mean anything if they played well. and all the lower division teams over performed, so i think i have a pretty good grasp on the whole thing.
i suppose my conclusion after all that rambling is, i am pretty convinced bingball is not the optimal strategy. especially outside of d3. but it is a damn good one to understand, and work into your own system. also, i think it is vulnerable to man/zone double teaming, especially outside of d3. but, it is shockingly effective. so effective, it might be acceptable to call it a glitch. but, there are still many questions. can you do the same thing with triangle/motion? i personally am pretty convinced the answer is, not as successfully. but still, more than you'd think. OR and lostmyth have both said, fairly recently, they feel offense doesn't affect how you set distro. i have always said it makes a big difference. who is right? all of us? none of us? its an interesting question no doubt, and to me, one of the most enjoyable parts of the game (trying to decipher the subtle differences in the 3 offenses).
