It's a good lineup on paper but they're relying on 3 6/7th year wrestlers who are in it for the bag, 2 of them with injury histories (Buchanan took a year off since he was injured and Teemer missed a year as well) I don't think total implosion or anything but that spells underachievement in Iowa.
That being said, I think Ayala improves at 133, Kueter will be a monster fully focused on wrestling and Caliendo impressed last year big time. Similarly the winner of their 174 wrestleoff I would definitely pick to AA though the one that has go to 184, I think is a tossup since they'll likely be small for the weight. Block is an intriguing prospect though I think he will be pulling a lot at 141 and he just missed a year and major ? at 125.
Of course if you ask HR, they have 8 finalists and Block and their 125 will probably sneak onto the podium and they'll score 173.
