Yes he belongs, Tinsley is an exception. Hard to look past the 2 teams he played on which were possibly 2 of the best teams ever at ISU plus his personal achievements can't be looked past either. Guys like Cato, Willoughby, and for some reason people mention Pratt (hopefully they are joking) just did not accomplish as much as he did in 2 years and were not all-american selections.
The 8 automatics I don't think you can really argue they don't belong on the list. The remaining list I just think there are more deserving players ahead of guys like Willoughby, Cato, and Vroman who push them just off the list of remaining selections. Here's a tough one to judge too... Cato or Homan. Homan played 4 years and is the all-time leading shot blocker but Cato played 2 years and set that record in 1/2 the time it took Homan to break it. Both made a NCAA tournament and both have pretty nice career achievements to support their case. I wish I had wrote down who I voted for but I'm pretty sure I didn't vote for either of them. They both did a lot while at ISU and while Cato is in the NBA I'm judging strictly on their time at ISU which I think is a near toss-up with possibly a slight edge to Cato just based on the contributions in a shorter time frame.
