Iowa was +6.1 ppg and +3.7 rebounds last year (and I'd bet the numbers were more heavily skewed in Iowa's favor at the time of the first meeting, since the stats were still heavy on the OOC games), and Michigan State didn't have any trouble matching up with us inside (not to mention the fact that Dawson completely shut White down).
We handled Minnesota inside, but their biggest weakness is inside. MSU had no trouble with Minnesota inside, either; the frontcourt guys outscored Minnesota 30-18 and outrebounded them 21-16. They also had 6 blocked shots. And Payne didn't even play.
I really don't see the shame in admitting that, despite statistical advantages in Iowa's favor going into the game, Michigan State can match up inside. We've got depth, but unless MSU gets in foul trouble with Payne and Dawson (and this is MSU we're talking about here; that's hardly a given, even in Carver), they'll be able to match alright. Plus, who's to say that WE won't get into foul trouble? Gabe, Woody and Mel all have a tendency to do just that, and they'll be drawing Payne a lot of the time, which means foul trouble is a definite possibility for them.
We aren't going to see 4 of our inside guys on the floor at the same time, and Dawson will almost certainly draw responsibility for White/Uthoff, which he's more than capable of handling. Uthoff is going to have to step up his game (averaging 7.6 ppg and 3 rpg in conference play), because Dawson will likely be on White whenever both are on the floor. Payne will have the advantage against any of the three guys we might throw at him (Woody, Gabe and Mel); he'll be one of the two best interior players on the floor, if not the best, at all times.
