NASHVILLE, Tenn. -- The group of offensive linemen the Tennessee Titans are likely to build around next season will feature fourth-year guard Chance Warmack, third-year tackle Taylor Lewan and second-year guard Jeremiah Poutasi.

That should cover it for youth, tight end Delanie Walker told The Tennessean.

"We don’t need another rookie lineman," Walker said. "Our offensive line, they’re too young. We don’t need another young guy on the line. We have eight picks, so use them wisely or trade to get older guys to come in and play the line -- savvy vets, eight-year guys or seven-year guys that understand how to win and know the game.

"I think that will help the O-line. But having a rookie come in and play with more rookies just doesn’t sit well with me, and probably not with Marcus (Mariota)."

It’s a great point, though I would trim Walker's experience requirement a bit. An ideal outside candidate would be heading into his second contract, and heading into his fifth or sixth season.

Among the linemen scheduled to reach free agency: Cincinnati right tackle Andre Smith, San Francisco guard Alex Boone, and left tackles Cordy Glenn of Buffalo and Russell Okung of Seattle.

Cleveland center Alex Mack can opt out of his contract.

At this stage, still not knowing who will be picking players or coaching them, I do not expect the team will aim to move Lewan from let tackle.
