Certainly the most polished. Honestly all 4 can succeed if they find the right fit and have some decent luck.
the guy that walks into a toxic locker room, gets injured in camp, has his OC fired in September, new head coach and gm next year, etc.... will bust... but generally I think all 4 if put into good spots will stick around at least serviceably. If Rosen doesn’t get any concussions he should be a mid tier guy at worst (think guys like Flacco, dalton, Schaub back in the day) and could be very good.
