The Cowboys are adding to their offensive line depth in this year's NFL Draft. Dallas selected offensive tackle Tyler Smith with the 24th overall pick. Smith comes in at 6-foot-4 and 324 pounds and ran a 5.02 second 40-yard dash at the NFL Combine. He did struggle with penalties last season for Tulsa as he was called for 16 penalties through 12 games. The Cowboys continue their draft today.
