Let's see whose career is longer and who does more for their team. I'm guessing because of the way Vick plays, he won't be around that long. He's constantly injured because of how he plays and it will ultimately yield him to have a short, relatively ineffective reign in the NFL whereas Manning, Brady, etc, will be effective for MANY years to come.
Ultimately Vick will be remembered as a fun player to watch but a guy who never could become a true NFL QB and thusly will never win a Super Bowl. A QBs first job is to manage the offense and pass. When the offense gets into long yardage situations, running is the not the solution, it's passing, something he clearly can not do yet. A passing QB sustains drives, eats times off the clock and is productive and effecient. With efficiency comes lack of turnovers, yet another HUGE knock on Vick.
He's may be a fun player to watch but he's not a franchise QB.
