This is a beast of a weight class. 2015 champ Tomasello of tOSU is (according to all reports) moving back down to 125 after being at 133 last year. He's at #1. Both of last year's finalists (Cruz & Lizak) are also back.
Nick Suriano will be allowed to compete this year for Rutgers after transferring from PSU. This was in the air all summer. For all the talent PSU has amassed in the past few years, 125 was a spot where they have very little depth.
The big unknown is what will happen with Iowa stud recruit Spencer Lee. Iowa likes to redshirt all their freshmen at the start of the season and make decisions at the semester break. Lee had ACL surgery in March, and Iowa isn't expected to contend for a team trophy, so it's possible they'll be extra cautious.
