From Last Week's New York Daily News :
You don’t have to be a body language expert to notice that Mark Sanchez has kept his emotions in check the past few weeks. He was the sketch of cool after his 74-yard touchdown pass to Braylon Edwards last week. Moments after firing a 52-yard completion to Santonio Holmes in overtime that set up the game-winning field goal, Sanchez simply clapped. He credited his calm demeanor to the new Bad Body Language fine system put in place by the rest of the quarterbacks.
“It’s a fun thing, but also a good coaching point from (Mark) Brunell,” Sanchez told me. “So I jumped on board right away. It’s really showed up and it’s kept us in some of these games.”
“Sometimes the hardest thing is to fight your emotions and deal with the rollercoaster of the game,” he added. “If you can show that even keel demeanor to the team, that stuff is contagious. When our team can see that from me, it resonates. They know, ‘Hey man, don’t mess with this guy in a tough situation. He’s ready.’”
Sanchez has done a good job of "staying in the middle," with his emotions the past couple weeks
“That’s the kind of demeanor that you want to have and the message you want to send to those guys,” Sanchez said. “Because you’re going to need it late in the game. You don’t want to get too excited off a 21-point lead, because it’s never enough. If you throw three picks in the first quarter, you can’t tank. You still have three more quarters to play. Who knows? These are long games. Crazier things have happened. So it’s just about staying in the middle. That’s the biggest coaching point.”
