Was Troup a bad pick? Yes. However what happens to the math if Troup becomes a serviceable journeyman in this league and Gronk never plays football again? Just a thought.
As for Terrence Cody, last I looked he's still not a starter but only a rotational player.
While you were incorrect about Carrington taking Kyle's job, this is a really good point.
Every GM has hits and misses. Buddy's tenure will be marked by his faith in Chan Gailey and Ryan Fitzpatrick. The correct point has been made in this forum a million times: talent across the NFL is fairly even. What separates winners from losers are coaching and quarterbacking.
Put a good coach and a good quarterback on a bad team and look how many journeymen suddenly become Pro Bowlers.
