The Dallas Cowboys had problems on offense last season, and one of the contributing factors was the decline in performance of their offensive line. The team endured a slew of injuries, but the biggest change occurred in the middle as the team was without two of their starters from the 2017 season. Left guard Jonathan Cooper left in free agency, and Travis Frederick missed the entire year after being diagnosed with Guillain-Barre Syndrome. Instead, the team relied on veteran Joe Looney to play center, while rookie Connor Williams took over at left guard.
