Heres a thought, lets assume because its wet both the 49ers and the Giants want to run the ball. And lets further assume both defenses are slowing if not stopping the run. And lets assume that Alex Smith, who has a reputation as a game manager, showed his growth against the Saints by throwing strikes and orchestrating 2 drives, leading his team to 2 TD's. Lets assume those 2 drives are the improved Alex Smith, and the Giants will face that improved Alex Smith.
So both defenses have stopped the run, and the 2 quarterbacks now have to throw the ball to win the game. Who do you think can carry his team to victory?
Thats why I have changed my view of this game, I was thinking GIants by 3, I'm now thinking GIants by 5.
