That’s part of the reason his teammates took exception to Sanchez drawing boos. Safety Jim Leonhard called the fans’ display "disappointing." Revis said it was "shocking." Keller promised that if any of those fans saw how hard Sanchez works, or understood what really happens on a play, they wouldn’t be booing the quarterback.
None of us are in the locker room so we cannot say for sure how things are in there. While this is a reality, it is also a reality that these players do not need to defend their quarterback from the fans. They could easily dismiss it as the fan's right without defending Sanchez or generating headlines. Keeping the locker room together can be a real challenge when a team is struggling. Failing to do so can destroy a season. While there is no substitute for more consistency on the field, the fact these guys are sticking together is a good sign.
