I was just looking at some stats and I realized that Sanchez has played so incredibly bad this year that he is actually rated lower than worst in the NFL in the three major statistical measurements:
QB Rating : 33rd
Total QBR : 37th
He is objectively not the worst starter in the NFL, he is so bad he is worse than the USFAs and 2nd string scrubs that play because of injuries and the like. And Tannenbraindead signed this guy to a guaranteed 2013 contract for a pittance of cap space, because he was upset at drafting Tebow.
Sanchec is a disease that needs to be excised. It is better to eat the cap hit than have this loser cancer suck the lifeblood out of the 2013 roster.
