*Indicates consensus All-American
Since the list was published following the 2004 season, I'd add Decker to the WR list (in place of Atwell), potentially add Eslinger to the OL list (although all five currently were consensus AA), potentially add Maroney or Barber to the RB list (in place of Thompson).
