Tennessee Titans expect improvement in run game

Titans HC Mike Munchak expects to see a big improvement from RB Chris Johnson and the rest of the ground game in 2012.  “I think he's excited to get last year behind him as we all are as far as the running game goes,” Munchak said. “We know it's not going to be worse, believe me. We feel like we're going to be able to make a drastic improvement from where we ended up."  Tennessee finished 31st in rushing last year.  Munchak cited a normal offseason for Johnson and another year in OC Chris Palmer's offense as reasons to expect an uptick in production.
