I believe the single game accomplishments are not position specific.....meaning the rushing could be for Vick or Bush and the receiving could be for Bush or Andre Johnson. This player just has to make that milestone. I believe it is just the season specifics that are completely position specific. But realize that if Reggie Bush received 225 yards....that owner wins, not the owner of Megatron......
