Their defense looks tough. If you aren't capable of breaking it down off the dribble or quick passing to expose their trap, you end up either turning it over or taking a bunch of jump shots.
Taking a lot of jumpers isn't necessarily a bad thing for ISU, though.
I'll say this: If Iowa is hitting their threes like they have in this game and last night (16-30 so far between the two games), they're going to be VERY tough to beat by almost anyone. They'll be a tough out, regardless, but (and I know this is still a big stretch until they keep it up for more than a couple games) they could give MSU a legitimate challenge for the conference title if they keep shooting this well. The defense is going to be there, and the inside will open up for White, Marble, etc. to drive if shots are falling from the outside.
I'm still picking ISU in Hilton, but only by 6-8 points. It's going to be an outstanding game that's a big boost to the winner's resume.
