alright in my scenario, Bledsoe gets speared at the end of the first half and a concussion so bad that not only does he think he's batman, he thinks Parcells is his dad. And he thinks he's in third grade. He tries to come out after halftime in his underwear but the trainers restrain him and in the end they have to lock him in a closet.
So Romo plays the second half until Keith Davis' ex girlfriend runs onto the sidelines and shoots him (4 times). Three of the bullets are lodged in his legs but one ricochets off the ghost of JFK and buries itself in Romo's shoulder. Parcell's inclination is to leave him in the game and just have him run the ball but the blood is flowing freely and the refs will have no part of that.
So Parcells is forced to go with third string QB...Quincy Carter!! QC starts off great, running a bootleg for a 4 yard gain on the first play, handing off to JJ for a first down, and finally completing an out to Terry Glenn. With time running down, QC takes it upon himself to run the ball into the endzone (to TOs consternation) only he is tackled 3 yards short and the game ends with the Colts ahead. QC is heartbroken at first, but later happy because he realizes this may provide him with another chance in the NFL or failing that with the Montreal Alouettes.
