Let's hear them now...
A few that come to mind right now:
1) There will not be an undefeated wrestler at 184
2) 149 will not be as tough
3) Ohio State has 3 champions (Jaggers, Pucillo, Sponseller in a vacated 165, Palmer, Humphrey as potential champs)
4) Metcalf does not win a second title
5) Gap between Ohio State and Iowa much closer, with OSU having as many as 8 AAs
