Minnesota went to the NIT final last year.....didn't really help a whole lot. Penn. St. won it in '09, well ummm, they are still Penn. St.
UNC was runner up in 2010 and went to the elite eight the following year. Baylor was runner up in '09 and in the elite eight the next year too. We can sit here all day and pull out examples of teams that improved or didn't the season following an NIT run. There's a ton of other variables involved here besides just their NIT finish, and looking at the Iowa program as a whole and the progress it has made the last three seasons and the talent coming back, all signs point to this being another stepping stone for us.
