Jerry Jones, in his first 23 years owning the Cowboys, never drafted an offensive lineman in the first round, yet had a strong line in the 1990s. Since selecting Tyron Smith in 2011, the Cowboys have picked multiple offensive linemen in the first round, with Tyler Booker becoming the third such pick in four years, set to replace the retired Zack Martin, a Hall of Famer. Booker, who primarily played left guard at Alabama, is ready to adapt to right guard and is focused on being himself while learning from Martin’s excellence.
