No, it doesn't, but it does state an expectation that you will execute your responsibility and not abandon it early to "make a play."
From my easy chair, Cassel in 2008 appeared to be executing the offense as designed, he didn't try to force things, and by being steady and patient he allowed the other players to execute their assignments and give the coaches a better framework for evaluating and correcting the execution. By contrast, the view from my easy chair considered Gutierrez to be more of a freelancer, and O'Connell to be scrambling mentally, leading to the same on the field.
You could go back another couple years to the Oscar Lua experiment/infatuation. Late in the game, Lua would be playing alongside Corey Mays; second year man Mays would execute his assignment as I understood it, while Lua was charging around leaving cutback lanes open and overrunning plays while he looked for someone to hit. More than one Lua fanatic took me to task for my critical assessment, but Corey Mays is on the Kansas City roster and Lua is out of football.
