From LNSmithee on the trib site:

"At Giant practice one day the OL was totally F-in' up. Parcells is yelling at them from the sideline. At break time Simms heads to the sideline and Parcells rips into him harder than he just had done to the OL.

Simms says to Tuna: 'What are you yelling at me for, I'm not the one screwing up?'

Parcells replies: 'You're the QB of this team, and yelling at the OL when they're F-in' up is your responsibility. It comes with the job and is part of leadership'. "
