You obviously struggle with the concepts of inference and proof and data. Your hypothesis is backwards, it is far more parsimonious to assume that Manning is average and then prove that he is not, then to assume he is exceptional and try to determine if he's not. If you start with exceptional then you always default to exceptional even when the data don't say anything one way or another. And even if you insist on setting up the assessment that way, the differences between us come down to what is adequate proof and what is the definition of exceptional. I think it is pretty reasonable to stakeout a very skeptical position regarding the quality of our basketball coaching given the garbage Welman trotted out on the sidelines for 4 years, while repeatedly assuring us everything was fine. Lots of people said Bz was a great X and O's coach. There were anecdotes about how when he was in Miami as an assistant he designed the in-bounds play that Prosser used years later from Chris Paul to score a buzzer beating layup against NC State, or there was that time he was coaching Navy and beat the shit out Wake. There were plenty of quotes from other coaches and players about what great hire Welman made. But no matter how many anecdotes and quotes you thrown together it's pretty undeniable that Bz sucked.
That 20% stat that RJ provided today is really impressive, but it's not conclusive. Four of those 5 guys were drafted when Manning was an assistant. It is highly probable that Bill Self did a little bit of coaching at Kansas too. Either way Manning has yet to replicate that success here except for JC. Manning has had 5 or 6 post players (depending on if you count Washington) here for more than one season and JC is the only one of 6 to show remarkable development, though after the last few games, Doral looks like he is on that path now, which is why I came here to post. It is not unreasonable to retain the suspicion that Manning got lucky with JC, like Odom did with Duncan, and his other players are performing pretty much as expected. I am, frankly, not as impressed with Dinos as RJ is. It's only been 3.2 seasons since he started here and I think it's is too early to conclude definitively if he is amazing and any aspect of the coaching job.
