I would literally puke if TJ ended up at Indiana next year.
Mendoza has another year at IU. However, keep the puke bucket nearby, just in case. The orange Home Depot kind.
These are the top places that will need to replace their SR QB
Miami - Carson Beck
Florida State - Tommy Castellanos (possible new HC)
Ole Miss - Trinidad Chambliss
Texas Tech - Behren Morton
Tennessee - Joey Aguilar
Clemson - Cade Klubnik
Georgia Tech - Haynes King
Vandy - Diego Pavia
LSU - Garrett Nussmeier (and new HC)
Baylor - Sawyer Robertson (Tied with Mendoza for most TD passes)
Missouri - Beaue Pribula
Arkansas - Taylen Green (and new HC)
Kansas - Jalon Daniels
Bold is just my own thoughts where he might receive a phone call of interest. But also consider Florida & Auburn if Lagway & Jackson Arnold leave because of new head coaches.
Personally, I think there is too much football left that needs to be played before anything can be seriously considered, with 2 very tough road games against good defenses. After Iowa, we'll talk Turkey (figuratively and literally - ha!)
FYI these places are good at QB next year (returning starters)
Ala, Georgia, Indy, tOSU, Texas, OU, Texas A&M, Oregon, SMU, Arizona State, Notre Dame, BYU, Wash, Arizona, K-State, Cincy, UCLA, Utah, Arizona, TCU, Iowa St, Duke, South Carolina
