The Titans are shuffling players along their offensive line, which produced a 2,000-yard rusher and allowed just 15 sacks in 2009. Eugene Amano is moving from left guard to center, while Leroy Harris has moved to left guard and the chance of being a full-time starter. Longtime center Kevin Mawae hasn't been re-signed by the team. "It's a real smooth transition," coach Jeff Fisher said Wednesday of the changes. "I would like to think they can play for a number of years together."
