This is about as accurate a statement as you'll find.
People say Wisconsin fans have said Uthoff isn't a good player only after he decided to transfer and were high on him while he was in Madison. That really isn't true. People were excited about Uthoff but certainly didn't see him as someone who would be one of the best 1-2 on the team during his career.
From what I heard regarding him was that he was smart, understood the game (if Bo Ryan recruits you, you are probably a smart player) had a nice touch and didn't force things. On the negative side, as others have stated he's very weak and probably won't ever be a banger/rebounder inside. He's a "3" offensively but on defense he's definitely a 4. He wasn't exceptionally quick so he'd have a hard time defending a 3 and probably a hard time keeping a 4 off of the glass.
As others have also noted there is a problem with finding a position for him at Iowa because Aaron White essentially plays what you'd have Uthoff play. If you play them together then you have 2 guys that are kind of between positions on defense. Offensively they'd be fine on the floor together. Uthoff isn't going to take minutes from White because White is just better at this point in time and while White isn't strong, he's stronger than Uthoff.
