Northern Iowa has really good computer numbers (i.e. #11 in Kenpom, OU is #10) and they gave Wichita State a beatdown earlier this season. Their defensive and offensive efficiency numbers are similar to OU. They won some tight games on the road. They play at a very slow/deliberate pace (#348 of 351 teams) which leads to alot of low-scoring games. But they shoot a really high% from the floor (#7 in eFG%) which means that they seem to be pretty good in the halfcourt. The achilles heel looks to be rebounding. If they miss, they don't get many offensive boards. They appear to be a quality mid-major.
But candidly, I've only seen clips of them....so all I have is computer numbers.
