The Facts: The 49ers unleashed yet another dual-threat QB on the NFL in 2012. With his nifty footwork on read-option runs and scrambles — and not to mention his strong right arm — Colin Kaepernick nearly produced a Super Bowl win. Other such signal-callers — Cam Newton in Carolina, Robert Griffin III in Washington, Russell Wilson in Seattle — gave DCs migraines as well. Locker’s skill-set is similar to those players, so will he be turned loose this fall to join the movement? HC Mike Munchak hinted that running could become a bigger part of the third-year pro’s arsenal. “Jake brings that dimension to the game, but you have to be smart about it. You want to take advantage of all the skills he does have, though it’s hard to survive if you’re running it all the time,’’ Munchak said. “So it has to be a happy medium, and that’s what we’ll try and find.”

Diehards Line:As Tennessean staffer Jim Wyatt notes, Locker’s running was limited last season to 291 yards after he suffered a shoulder injury in the season opener while making a tackle. He eventually missed five games and had surgery after the season, but he is on track to be fully recovered for training camp. OC Dowell Loggains said the Titans planned to study other teams with similar quarterbacks to explore some pistol or read-option plays that were so successful. ... The concerns, of course, are obvious. Munchak pointed out that Griffin was unable to finish last season because of injury, and Michael Vick has taken a pounding over the years. "maybe we wouldn’t do it to the degree you have seen other teams do it," Munchak said. "Because I don’t know if the quarterback can hold up doing that." In Locker's case, it has to be a consideration.
