Tim Tebow is a commodity when it comes to messing things up for defensive coordinators, making it hard for them to game plan for him when they don’t know his involvement in the packages or the game plan. Belichick, as we all know, is a smart guy. If he could add a weapon to his offense, whether he’s going to play him or not play him, and defenses have to spend time in practices and film sessions to prepare for what they may or may not see, this takes away from the overall preparation when it comes to preparing for an offense that is already very difficult to stop.
