It might be hard to believe, but just a couple of years ago fans of the Dallas Cowboys were feeling really good about the state of the offensive line. Three of their lineman were coming off of Pro Bowl seasons, Tyron Smith, Zack Martin, and Travis Frederick (who returned in 2019 after missing the previous year dealing with Guillain-Barre syndrome). La’el Collins was coming off his best season as a pro and many suspected Pro Bowl appearances were in his future. And their weakest link, Connor Williams. was still young and showed a lot of potential.
