I know I'm in the minority here, but I don't what Rosen leading the qb battle in camp and getting the traditional number of starter preseason game reps. I want him playing two quarters or more per preseason game in the back up role and seeing as much game action as possible.
If Fitzpatrick starts the regular season I don't see the big deal. It would likely come down to if Ryan continues to play lights out and the team is having success than he keeps the job. However, if the team struggles and Fitzpatrick has his ups and downs than he'll lose the job and they'll put Rosen in. SO the it's either the team plays well under FItzpatrick and wins games or Rosen plays. Sounds like a win/win to me. You'll either have a winning team under Fitzpatrick or a have Rosen start 10 or 11 games instead of 16. That would still be enough action from Rosen for him to grow and the team to access his progress and potential.
