Consider this unofficial info but I compared the 2021 roster with the 2022 roster. There are 112 players listed on the current 2022 roster on the iufb website. I counted 56 players from last year's squad who either graduated, declared for the NFL draft, entered the transfer portal or otherwise left. That's literally half of the roster. I realize the transfer portal has changed the offseason dynamic but this still seems like a very high number. Taken together with the coaching turnover / new coordinators it may be unrealistic not to expect some growing pains.
(Note: I am more than happy to crowdsource this. Feel free to add additional info if you have it or to correct any mistakes I have unintentionally made. I don't have an editor to bail me out lol. I just ask for a source - if you don't have one I won't make an update.)
