You do realize that Manning was selected #1 overall and turned his team around almost immediately? Teams that are loaded with talent don't select #1 overall.
They do when their QB is named Jim Harbaugh... Once again, not a knock to Manning, but look at Detroit, terrible team but give them an elite QB, they're 10-6 instead of 6-10. As mentioned before, Harrison and Faulk/James aren't scrubs... QB was the missing piece to the puzzle in Indy...
