FRISCO – There is a change in the offensive line of the Dallas Cowboys in the form of a youth movement.

And there also might be a change in the form of Tyler Guyton.

Future Hall-of-Famer Zack Martin announced his retirement from football this offseason after more than a decade of stellar play. Shortly thereafter, another Dallas legend, Tyron Smith, finished his one-year stint with the New York Jets and “retired as a Cowboy.”

Now in this “new era”, Cowboys fans are forced to move on, too.

So who’s got next?

Cowboys fans already have an idea that this year’s first-round rookie, right guard Tyler Booker, is a future star.

They are less convinced that another next great offensive lineman is left tackle Tyler Guyton.

But the Oklahoma product, drafted at pick No. 29 by Dallas in last year’s draft, is impressing his new coaching staff this offseason.

“Tyler Guyton has been in the weight room every day. He’s working his (butt) off,” new coach Brian Schottenheimer recently said. “To me, that’s really exciting.”

The offensive-minded head coach mentioned the influence that new offensive coordinator Klayton Adams and another new top aide have imprinted on his young linemen.
