Manning, Brady, Brees and Rodger are all clearly franchise QBs regardless of who is best.
Revis pre-injury was approaching shutdown during his Revis island phase.
Sherman isn't even close as can be demonstrated by the Texans game. The Texans went after him all day long. Clearly he was not feared and avoided (although he should have been on the pick 6).
Deion was truly shutdown. QBs largely refrained from even throwing in his direction.
Just exploring all angles how one defines such questions with draft rankings/value per position @ forefront. I defer these questions to my fellow Texans, I never lay any claim to being an expert on these things. I can scout College to Pro but after that there are so many influencing factors to consider sometimes unrelated to their actual grade.
Really enjoy everyone's input, including yours
