At least other teams are struggling this year.
On this play, Sanchez tries to hand off the ball to his RB but apparently the RB forgot this was a running play. Sanchez improvises and tries to run the ball upfield and gets a mouth full of his offensive lineman's butt, then fumbles the ball for a TD.
This was all part of a period of time where New England scored 3 TD's in 55 seconds.
Not even Cassel can claim ownership of a play this bad.
