The Titans have signed tight end Craig Stevens to a new four-year contract. Agent Kenneth Zuckerman said Friday that the four-year deal is the first since the NFL season ended taking advantage of the new labor deal rewarding veterans hitting free agency for production over rookies. "Obviously by the terms and the deal, he saw how valuable he was to that team and how important he was," Zuckerman said. "He's real excited to get this behind him and start to prove to everyone that he’s worth it." The 6-foot-3, 268-pound Stevens was a third-round draft pick out of California in 2008 and has 24 starts over the past two seasons.
