By the end of the 2012 season, "disarray" would be a nice way of describing the Titans' interior offensive line.

The three projected starters (left guard Steve Hutchinson, center Eugene Amano and right guard Leroy Harris), along with one key reserve (center/guard Kevin Matthews), all had been lost to injury, leaving the Titans with a makeshift group of Fernando Velasco, Kyle DeVan and Deuce Lutui.

Don't hold your breath waiting for a reunion of the original trio, either. Harris is a pending unrestricted free agent; Hutchinson will have to decide whether he wants to continue playing; and Amano could be cut loose with two expensive years still remaining on his contract.

But if there's a good year for a makeover at guard and center, this might be it.

General manager Ruston Webster is cautiously optimistic the Titans will have some free-agent options in March. As for the draft, ESPN's Mel Kiper said interior linemen — especially guards — form one of the deepest groups among this year's prospects.

"This is an outstanding group," Kiper said. "It's as good a group as you'll find in terms of the early portion of the draft. There are a lot of guard-centers that have versatility, that can play a variety of positions. It's a very good group of guards, a couple of nice center prospects."

The Titans' offensive line troubles in 2012 began early in training camp, when Amano was lost for the season with a triceps injury.

Harris was knocked out halfway through the year with a knee injury; Hutchinon was lost after 12 games with a knee injury; and Matthews missed the final two games with an ankle injury.

Considering that tackle David Stewart also missed four games with a broken leg, it's not a big surprise that the Titans finished 21st in the NFL in rushing, averaging 105 yards a game.
