I wouldn't be surprised if the guy TT looked long and hard at was Tyler Marz at the UW Pro Day. He's pretty similar to a Sitton/Lang and would be a middle-rounder. While Bakhtiari isn't a superstar LT, he's a battler and I think TT re-signs him for youth/continuity, though he could probably switch positions also.
Noah Spence makes sense to take a long look at. He's extremely talented, but has he grown up at all?
