Upstater - OSU's biggest problem in that game was Wichita going 8-20 from three while they went 5 of 25. Some of that was probably defense, but most of it was probably unfortunate statistical variance. Their other problem is not having a shotblocker inside - Craft, Scott, and Smith Jr. are all exceptional defenders on the perimeter, however nobody on their team blocks shots with any regularity.
I'm not making OSU out to be a juggernaut because they're not, but if you think a Wichita team that struggled that mightily with OSU's press will survive Louisville's press, you are sadly mistaken. Don't confuse my opinion here with me thinking they didn't earn their spot in Atlanta, because they certainly did, and they are a good team. But the talent disparity between OSU and Wichita was pretty wide. Wichita was simply more well-coached, tougher, and hungrier today.
