Question about scoring a TD w/ less than 2 mins.

[Matt Williams]

Wouldn't it be better to run the ball out at the 1 yard line or get tackled and take time off the clock before punching the ball into the endzone? How many times do you see a game where one team scores but leaves 1-2 mins. on the clock giving the opponent a chance to win? Now I know no NFL coach would ever do that nor tell his players to run out at the 1, but would it be +EV to do so?
