This article goes into more depth of what Matt Leinart had to do during his MMA training over the offseason.. We saw a little bit of this toughness show in the St. Louis game when he shook off a defender and threw a bullet to Early Doucet.
Jay Glazer's thoughts on Leinart: "The Matt Leinart I knew was some prissy pretty boy who I would love to have fought in two seconds," he says. "But he's not the same Matt Leinart."
The 49er's Patrick Willis also did these workouts to toughen him self up, like he needed to get any tougher.
Very interesting article.
