wilson, flacco and ryan had EASILY better teams around them
all of these teams besides the colts were run-first teams as well, and you can argue colts werent as bad as their record indicated the year before luck because they expected peyton to start for them and team just quit mid season.
grooming a qb for a bit is still the best option out there, unless you need immediate results right now or youre fired

all sat behind existing qbs, and Im pretty sure all are heading into hall of fame
