Eh, I think he made some bad choices, but I don't think it was one of those "lesson" games, like leaving Ward on the bench for a whole half against Rutgers. Or doing weird lineup things in a marquee December game.
I think this is his deepest team, and he's struggling with cutting down the rotation. When the team is clicking, it's fine. When they aren't I think it's going to be problematic. MSU jumps out to an 11-4 lead. So he brings in a couple walk ons and deep rotation guys at the 16 minute mark of the first half? MSU lost all momentum when he decided to trot out Naird, McQuaid, Goins and Schilling 4 minutes into the game. He brought the starters back, and then again went to that deep rotation. After he did that wholesale lineup change, it was 37-18 OSU for the rest of the half.
When MSU is feeling it, it gives guys rest, when they aren't it's just breaking up their momentum, and prevent the offense from ever getting into a groove. Usually he's pared the rotation down more by this point, but this year he hasn't, and I'm not sure that's ideal for a March run. Yesterday may have been a lesson game, but perhaps the lesson was to Izzo, that he may have to make some tough choices when it comes to cutting the minutes of certain guys.
