I am currently watching the Cards/Bears game on NFL Replay. Leinart has not shown me great arm strength, yet he passed the ball with great efficiency and accuracy. I also think of Tom Brady as a QB without great arm strength, but with great accuracy.

My point is that we don't need McNair to have a "big arm" a la Kyle Boller. If McNair can cure this uncharacteristic lack of accuracy, we are going to be fine on offense.

Screw having a big arm. Once McNair finds his accuracy, the positive difference will manifest.
