SUMMARY: According to Titans Coach Jeff Fisher, LB Peter Sirmon's job appears safe for now at middle linebacker despite quality play by rookie Stephen Tulloch. "Pete's obviously ahead because he understands the game, the concepts, the coverages, huddle calls and all those kind of things," Fisher said. "Stephen is still learning and he's not a repeat mistake-maker, which is good. He's learning and he's very athletic. He can line up and just instinctively find it without relying on an understanding of the scheme. Sometimes that's good and sometimes that's not good." Tulloch made six tackles while recovering a fumble playing with the second team defense on Saturday. What do you think about this article? Post your comments below.
