To get Peyton Manning or Mike Vick for a low draft pick what you do is go into "view roster" look at the team they are on and select them then it should show their prestiege and all of that, on the list to the left hand side of the screen select edit player, there you can change the players posistion. Example: Peyton Manning to WR then go to "Trade For Player" and trade a low pick for him, then once you have aquired him, edit him back to QB and you will have gotten Peyton Manning for a low draft pick.
