Rosen is owed backup QB money the next three years with a 5th year option. Money will not prevent Miami from selecting a QB next year as they’ll have plenty of cap space and Rosen is dirt cheap.
If he becomes a franchise QB, it’s an all-time great trade. If he doesn’t, they burnt a second rounder and they likely lost a bunch of games and can still draft a QB in 2020 or 2021.
Have to assume Flores and O’Shea are somewhat familiar with him as it seems the Patriots liked him pre-draft. I’m in favor of shooting their shot and being ok if he flames out and they draft someone next year.
