remember
1. that 2 of those QB sneaks last week were ones they ran NOT TO GET INTO THE ENDZONE; but rather for TB to go down on the 1/2 yd line and burn the clock. They looked ugly; like he was taking hits; but he really wasn't.
2. That usually when TB runs the QB sneak it is on short yardage to a 1st down when the D leaves one of the center gaps uncovered. He isn't taking much of a hit when he is just following the OL in a vacant spot and going down.
Anyway; I dont see him 'not using his left arm right' after those plays and if so it certainly looks more attributable to that crunch by the cameron wake sack at 3m left in the first half. If that is the case then he may have been tender with the left arm. but it could have occurred at any time prior to the play you think it happened in, the wake sack or other. He did get hit a lot in the first half.
