Kurt Warner: Did Rattler even have a chance against the Chargers?

We were still in the game when Rattler was pulled. Penalties and pressure killed our offense, not QB play. I can see playing the third QB if the game were out of hand. Seemed like an act of desperation to pull Rattler.
We were desperate, desperate for some offense. Again, I like Rattler, but he was OFF in that game. He was missing EASY throws. He got pulled to try and spark the offense.
