Vick & Young may not put up the stats that you obsess over in a QB -- but they execute on the stat that matters most: W's. They have managed to win games despite lackluster talent around them. And of course, leave it to you to even try and compare JP Losman to Vick. Vick has had great success in the league, very early in his career. He's made 3 Pro Bowls, he has led his team to division titles, and he's won a road playoff game -- this despite not having a reliable wide receiver to throw to.
Yeah, the coaches were real inept for leaving him in there.
Young also had success relatively quickly reaching the playoffs and getting a Pro Bowl nod in his second year as a starter. And the talent at the offensive skill positions is nonexistent! But I suppose Jeff Fisher doesn't know what he's doing, too.
Thankfully, the Bills brass disagrees with your assessment on JP and realized pretty quickly that JP wasn't the answer and have put their faith in the youngster.
You were awfully quick to jump to conclusions on Vick's affiliation with dogfighting because it happened at a property he owned. Yet you're suddenly a proponent of "waiting for the facts" in deciding whether or not Marshawn was involved in a hit-and-run with a car that he owns. Truly irony at its best.
