J.J. McCarthy, Most Likely
No decision will affect Michigan's roster as much as the impending choice for quarterback J.J. McCarthy. Will he enter the 2024 NFL draft or return for his senior year? Also, is that verdict tied to Harbaugh's future? McCarthy is not viewed as an elite-tier prospect but would likely be a first-round selection, and that is—in my opinion, which certainly may be wrong—enough for him to chase the pros.
Offense, Offense, Offense
Regardless of McCarthy's pick, the Wolverines may need to overhaul the rest of the offense. Running back Blake Corum, wideout Roman Wilson and offensive linemen Zak Zinter, Trevor Keegan, Karsen Barnhart and Drake Nugent all could declare for the draft. Wide receiver Cornelius Johnson and left tackle LaDarius Henderson are out of eligibility, and tight end AJ Barner may leave, too.
Defense, Defense, Defense
Although the Wolverines have a sturdy returning group, the defense is headed for major transition as well. Defensive lineman Kris Jenkins, edge-rushers Jaylen Harrell and Braiden McGregor, linebacker Junior Colson and safeties Rod Moore and Makari Paige all have NFL futures. Defensive tackle Cam Goode, linebacker Michael Barrett and nickelback Mike Sainristil have used up their eligibility.
