People will say that he wasn't ready, or was ill-prepared, or didn't play defense...bottom line, the kid was always ready (as I've said all along). You can tell his fundamentals (he's a Hopkins product after all) are far ahead of a typical freshman, as is most of his decision-making and spacing.
The problem was you'd throw him out there with the 2nd five (Oto, Ingram, Armelin, etc.), only play him 3-4 min at a time, and of course it looked like everyone didn't know what was going on. Especially for a freshman, he never got a chance to get in the flow of the game.
Tubby finally gave him some decent PT and a chance to settle in with the starting 5 guys, and he's had a chance to excel and show what he can do. Couple that with we have gotten away from the god-awful high-low offense that we had when Mbakwe was playing (trying to capitalize on both RSIII and Mbakwe in at the same time), and the new offense has allowed some penetration space for the guards from the top of the key and the wings.
Thus, I'd say Coleman & Welch have excelled the most since the move to the 3 guard line-up because they actually have some room to create & penetrate...where within the high-low offense we've been running the past 3-4 years, the guards have had nowhere to go. If they attempt to drive, there was always 1 or 2 posts on the block, stifling any room they had to drive.
To to sum it up, a number of things...
