More than likely Crabtree had been talking shit all game and he just wanted to let everyone know about it lol
Why in the hell do you throw the ball at the best corner on the opposing team, probably the league (he led the NFL with 8 ints) in one of the biggest moments in the game.
Great players make great plays when it counts. There is no way I'm throwing that ball anywhere near Sherman. Maybe Manning or Brady get away with that throw, but not Kaep
