A second Super Bowl win in the last four seasons did not quench Justin Tuck's thirst. In fact, the New York Giants' defensive end was underwhelmed with his own injury-riddled campaign and has been working out with renewed vigor to return healthy and improved in 2012.

"I really never stopped working," defensive captain Justin Tuck said today after participating in the team's offseason workouts. "This is your first day seeing me but I've been here a lot. It really isn't any different for me other than everybody else is in here."

"I'm just working harder," he said. "Last year, with all of the uncertainty around football, I might've laxed a little bit in my regimens. But I guarantee you that won't be the case this year."
