When the Titans signed free-agent linebacker Moise Fokou in March, the conventional wisdom was that he’d be a valuable depth player in case of further injury to Colin McCarthy. It doesn’t appear, however, that anyone alerted Fokou to conventional wisdom. Although there’s still a long way to go before the 2013 season, it has been Fokou who has been holding down the first-team middle linebacker position in organized team activities. McCarthy is still working his way back to 100 percent after ankle surgery, but Fokou, who played for the Colts last season, has made a strong early showing. “He’s here, in his mind, to start. That’s how it should be,” coach Mike Munchak said. “He’s got a lot of confidence. He’s flying around the field. He has great speed. He is a communicator. So he’s what we hoped he’d be — so far, so good.” The 27-year-old Fokou (pronounced FOE-koo) endured a bit of a bumpy off-the-field start to his Titans tenure, when it was revealed last month he’d been charged with DUI in Washington, D.C., in February. Fokou’s lawyer has contested the charge, and a trial has been set for October. The fifth-year pro’s transition on the field has been much smoother, especially since he’s making the switch from a 3-4 system to a 4-3. It helps that Fokou played in the 4-3 during a stint with the Eagles and in college at Maryland. “His keys are a little different now,” Titans linebackers coach Chet Parlavecchio said. “He’ll be keying now on the center-to-guard-to-fullback triangle, whereas in the 3-4 you’re lining up over the guard the majority of the time. But that’s one of those things that gets overrated a little bit. He’s a linebacker. If you’re fundamentally sound, you can play in any system.” At 6-foot-1, 236 pounds, Fokou looks like a more traditional 3-4 inside linebacker, as opposed to the bigger 4-3 middle linebackers. But Munchak doesn’t think that will hold back Fokou, who has also played both outside linebacker spots as a pro.
