At the most convenient time. (And by convenient, I mean at the most non-convenient time.) I don't think he throws one but then again...
He won't throw one. Schaub's confidence has to be shattered and I expect him to be even more cautious than before. Look for him to be even quicker to throw balls away and take sacks instead of trying to make a plays. I know I know, it's hard to imagine Schaub falling down faster than he does now. Texans have to run the ball successfully Sunday or Schaub will be traumatized by the 49ers pass rush.
