He deserves a lot of credit for finally putting Craft on the court extended minutes with Shannon Scott. That has, without a single doubt, saved the season. At first glance, putting 2 average sized PG's in the game, who are both suspect outside shooters to put it mildly, would seem like death. Thad early on tried to use Shannon to spell Aaron and they'd play together for about 13 minutes a game. Shannon was only getting about 20 minutes a game total.
The problem is, this team can't shoot even if you're running Aaron Craft with Sam Thompson or Lenzelle Smith (who has been in a funk all Big 10 season outside of Northwestern game) at the 2g. Once you realize the shooting is really poor either way, there is very little downside to playing Craft and Scott together for extended minutes. Shannon Scott has been an All Big 10 defender this year and everyone knows how good Craft is on the ball. When they play together Craft takes the 2g primarily and has done a very good job.
Offensively, Shannon Scott can't shoot a lick, but he's probably the fastest player with the ball in his hands in the country in transition. The only other guy close is Trey Burke, and while Trey is a much better player, he doesn't carry the same speed Shannon does end-line to end-line. It just helps the Buckeyes offensively so much when they have 2 PG's on the court that can get the ball and go in an effort for transition buckets. But even if they have to get into a set offensively, Shannon and Aaron have both been exceptional over the last 3-4 games of dribble drive penetration and kicking out. It's been like watching a different team.
The other thing I'd give Thad a lot of credit for, is his willingness to play DeShaun Thomas at center. I haven't seen anyone mention it. Against Northwestern he pulled it out of the bag when they were using an unskilled center in the paint that provided very little scoring threat. They let Thomas check him defensively, while Thomas scorched Northwestern in the middle of their 2-3 match-up zone. Thad brought LaQuinton in as a PF, and the Buckeyes ran a 4 out 1 in offense, and literally every time DeShaun caught the ball at the free-throw line he turned it into easy buckets. It was a fantastic coaching move to pull Amir and Ravenal who weren't giving them anything inside.
Against Indiana Thad went back to Thomas at center for about 7 minutes when Zeller got into foul trouble. Indianas back-up center is a lumbering dude, who does no more than hand the ball off in the high post, so Thad let DeShaun play the 5. In that span the Buckeyes pulled ahead in the first half and got a lot of momentum going. In both instances (Northwestern and Indiana game) he showed a penchant for understanding match-ups and utilizing a line-up that would be ultra difficult for the opposition to defend. And if you're going to throw a stiff out at center whom Thad would like to see shoot, he has no issue taking an undersized PF who can score anywhere from on the court and playing him at the 5.
