The Jacksonville Jaguars and defensive back Rashean Mathis agreed to a $25.5 million five-year contract extension Tuesday that will keep Mathis in Jacksonville through the 2011 season. The deal includes $9.4 million in guaranteed money in signing and roster bonuses. "I kind of get a little tongue-tied when I try to describe it,'' he said. "I love being here and I love that I have this new contract. It's a great feeling. You couldn't paint a better picture.''
