Well, I certainly have no problem making players "earn it". Anything less has the ring of favoritism.I really like the "structure" of everything you've said here and I agree with the majority of it.
I would add that if Flores and Co truly believe in the Patriots way of players playing then Rosen doesn't play for the rest of the year.
They truely seem to have a "general" phiolosphy that you have to "earn" you're playing time.
We've all heard the stories about Bellichect and Co. quizzing players on the most random things.
If something similiar exist then Rosen likely isn't seeing the field. Essentially he has to "know more" or "do more" or at the very least "be on the same footing" as Fitz.
Point being, I don't see them just giving him a start. He has to earn it!
As for Rosen starting earlier in the season, that has upper management written all over it and not some Flores wanted.
In this case though, they may see it as benificial in the long run, to have Josh take some "live" snaps, going into the offseason.
I can see it from both a confidence standpoint, as well as a measuring stick.
