Titans coach Mike Munchak said Tuesday running back Chris Johnson is starting to believe more in the offensive system.

"I think there’s no doubt he’s more comfortable," Munchak said, per NFL.com. "I think the first year I was here we had the lockout, and he held out. He had never experienced that. That made that year kind of strange, the whole year. We never really got that back it seemed like. Then the system was changed. It was a different play-caller, a different way we were doing things. I think he just feels good about everything. I think he’s had a good camp. I think he’s excited about the guys around him with the offensive line, the way Dowell (Loggains) is calling the game. I think everyone sees positives there that they’re all part of it."

Munchak added Johnson appears to be running more decisively this year.

"I think the holes have been better, so I think it allows the confidence to grow and the decisiveness to be what it has been," he said. "So, that has shown I think. The first three weeks has been a cleaner look for him. He’s getting a lot more reps. He’s got a quite a few reps even though the first game he only got two. The last couple weeks he’s gotten his fair share of reps, so he’s very comfortable with what we’re trying to do."
