Okay, no QB sneak on 4th and 1, and how many times has TB run out of the pocket this year? I cannot recall any, so if he has, it has been minimal.
Teams know that they can rush TB and he is just a target back there. So, either he (a) delivers a perfect pass to his receivers; (b) it is an incomplete pass; (c) there is an interception; or (d) a sack. 3 out of 4 are good options for the opposing D.
Also, when is Randy Moss going to fight for a pass against a DB? That interception in the end zone clearly could have been tipped away if nothing else.
