17-year coaching veteran Frank Smith joins the Bolts as run game coordinator/offensive line coach. Over the last three seasons as the tight ends coach for the Raiders, Smith helped develop Darren Waller into one of the league's top tight ends. Waller, a 2021 Pro Bowl selection, led all NFL tight ends with 107 receptions last season, as he recorded his second-consecutive 1,100-plus receiving-yard campaign. As an offensive assistant from 2012-14 with the New Orleans Saints, Smith worked primarily with the offensive line, tutoring three linemen earned Pro Bowl nods and helping Jahri Evans to a pair of All-Pro selections. Smith's experience in offensive line development can be traced back to his playing career, where he was a three-year starter along the offensive front at Miami (Ohio) University, protecting the eventual No. 11 selection in the 2004 NFL Draft, Ben Roethlisberger.
