Good teams struggle with tough turds all the time. If this becomes the norm, I'd be more worried. Since they won, and demolished another team of equal or slightly more talent than this one, I'd venture to say today was an anomaly.
I've watch two full games of UNCW now, UNO is a better team. It's weird since they're not even eligible for the NCAA tournament, but they were more athletic and bigger than UNCW.
That said Iowa made SEVEN less field goals in a win. It was a homer job. White was attacking the basket and earned his free throws. Most of the rest were a gift. UNO's guards were attacking the basket much more than Iowa's, yet Marble got 14 free throws while UNO's guards who attacked much more got 6, 2, and 2. It's a win, but wouldn't have been a win in any other building.
Iowa is not good at shooting a basketball, they put the basket in the hoop 21 times without the refs helping against a bad team. They'll win some games and make the dance, but I'll be shocked if they even sniff the astronomical expectations of Iowa fans.
