With the offseason basically wrapped up, it’s a good time to look back at the personnel across the college football landscape. I scoured the rosters and selected my favorite move by each Power 4 team.This is not limited to a transfer addition or a hot recruit.

As were the hiring of assistant coaches.ACCBoston College: Bill O’Brien taking over play callingFinding a move I liked for BC was a tough assignment. The Eagles lost six starters to the portal and their offensive coordinator to the NFL following a 2-10 season. The good news is O’Brien was a pretty good play caller at Alabama under Nick Saban and in New England when Tom Brady was his quarterback. Of course, there’s a bit of a talent difference between those places and Chestnut Hill.Cal: Bolstering JKS’s supporting castNew coach Tosh Lupoi and general manager Ron Rivera feel like a dangerous combination in Berkeley. Keeping QB Jaron-Keawe Sagapolutele was an obvious victory. Bringing in running back Adam Mohammed (Washington), receivers Ian Strong (Rutgers) and Chase Hendricks (Ohio) and tight end Dorian Thomas (New Mexico) will pay immediate dividends.Clemson: Adding speedy Chris Johnson to the backfieldDabo Swinney is recycling his former offensive coordinator Chad Morris after the Garrett Riley hire didn’t pan out. Johnson, a former Miami signee, has track speed and averaged 7.1 yards per rushing attempt at SMU in 2026. Will he solve all of Clemson’s woes? No. But he’ll help.
