New head coach is going to want his find own QB. It's going to be tricky when they bench Eli for the new guy it will piss off some fans, media and former players, but it has to happen and for that reason I wouldn't even bring Eli back especially at his high price tag. Darnold is not NFL ready, but would learn how to fix his mechanics and read defenses from an NFL QB coach more than what he would learn going back to USC. Rosen is the most pro ready and I think ultimately ends up #1
