I remember Sanchez batting down a pass on 4th down for a turnover on downs. I would call someone terrible if they were crap all game, and did nothing positive. That was a very positive play. It's the one that stands out for me, I'm sure there were a couple more.
Oh, another was that he got a good lick on the QB. It wasn't a sack, but it certainly caused him to hurry it, and I believe it took him out of the game. I guess that could be a negative since the backup seemed to play better.
