Offensive lineman Alex Leatherwood was a surprise pick for the Raiders.Credit...Brynn Anderson/Associated Press The Las Vegas Raiders, eager to replenish their offensive line, took Alex Leatherwood of Alabama. Last year, Leatherwood (6-foot-5, 312 pounds) won the Outland Trophy given to the best interior lineman in college football, after allowing just five sacks in 1,400 pass-block snaps. Still, the pick was something of a surprise because other higher ranked linemen were available ahead of him. The Raiders lost Trent Brown, Gabe Jackson and Rodney Hudson this off-season, so they were looking for a lineman to help protect quarterback Derek Carr. The Raiders had the 10th best offense in the league last year.
