Value to the team is WAAAAY overrated. And the reason I say that is because the front office has done such a poor job of surrounding him with good players. The majority of the players are either system players, scored high on the wonderlic, or were perceived to be "good guys".
I would like to see the Colts draft good players period!!!!!!! No way Donald Brown should be on the roster. Beanie was actually the better back, still is, but Brown was perceived to be the better fit. Now the Colts are paying for it.
Bottom line is: Peyton Manning is so invaluable because the majority of other players (especially back up QB), is pretty average!!
