Cowboys' first-round rookie Tyler Guyton is already doing exactly what he needs to for a fast start in the NFL

Dallas Cowboys fans will love to see the latest clip behind the scenes of the team's first-round draft pick, Tyler Guyton.

The offensive tackle out of Oklahoma is already hard at work ahead of his rookie season, which is the case for every other player that joined an NFL team last week. However, the key is how and most importantly, who, Guyton is working with.

Unsurprisingly, Guyton is already working out with offensive line guru Duke Manyweather, who works with many of the league's top players and who has established himself as the ultimate OL private coach at the NFL level.

The Cowboys have known how to leverage Manyweather's presence near the team's headquarters at The Star. The coach has worked with many Cowboys' starting linemen including Tyler Smith, who was once considered to be in a similar spot as Guyton as a developmental player. 

The below clip shows Guyton working with Manyweather but that's not it, you can see the first-round rookie working with his hands in a pass pro stance. Coming out of college, Guyton's inconsistent technique was considered his biggest flaw as a prospect.
