It's easy to understand now how in 2015, when Kyle Williams was lost for the season with injury, the lockeroom went down as well with the likes of Dareus or Mario Williams trying to lead this team.
Without Kyle Williams' day to day guidance, they started questioning Rex Ryan's defense. I'm not trying to give a pass to Ryan but you can't be a malcontent when you don't like certain things.
You have a problem with the coach, talk to him, you don't give up on an assigment, you don't fail to chip a TE going out on a passing route. Sompe players didn't care after Kyle Williams and it was embarrasing to watch (as was Ryan, though, but my point remains)
You go out and do your best, always.
