With Marcus Mariota looking like their future at quarterback the Titans need to find a left tackle that can protect his blind side for the next ten years. Mariota missed four games in 2015 and the Titans want to remedy that. Laremy Tunsil is the top offensive tackle in the draft and is great in pass protection. He could step in immediately at left tackle and give the Titans an anchor for their offensive line for the next ten years.Some mock drafts have the Titans taking Joey Bosa. Bosa is a worthy pick at number one and the Titans could use more play makers on defense.
