The only way I can think of where you can do that and not deal with all the offseason stuff if to play CFM as player, but problem there is you don't have full control of anything. Yes you don't have to do any offseason acquisitions, but you don't have any control over who stays, who goes, you don't have any control of play-calling, or playing the offense or defense, just that player. You could set up a coach or owner and have all the offseason stuff delegated to the CPU, but again, like roll2tide said, you'll have guys retire, leave for bigger contracts, so on so forth.
