I don't think the receiving core of Thrash, Mitchell and Pinkston are comparable to anything Manning has had to throw too. The one year Mcnabb had a legit option they made the Superbowl. That's one less appearance than Manning who has pretty much always had great wideouts. By the time the Eagles finally got another solid group around him he was already too old. I wonder what Mcnabb's career would be if he had Marvin or Reggie for those 4 years they made the NFC championship games.
