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.
Said "Schotty'': "I think the influence of Klayton, the influence of (O-line coach) Connor Riley, I think that package was so important for us, and I think we hit a home run."
Riley, Dallas' new offensive line coach, takes over a unit that features more youth than just Guyton. The longest tenured lineman now becomes Terence Steele, who enters just his sixth season in Dallas.
Cooper Beebe, who turned into the Cowboys starting center last year, was also a rookie. Tyler Smith, a 2022 draft pick, has continued to develop at guard alongside Guyton and is a star. Booker should be fine.
But what of Tyler Guyton? We have often said that the 6-7, 322-pounder - who last year drew just 18 penalties in his 15 games played, 11 of those games being starts - needed to get in the weight room to change a long frame that is (relatively) soft.
And now that Dallas is into OTAs? We are getting a look at a "new'' Guyton ... and a familiar Cowboys Nation debate: What do these photos really show?
The biggest room for improvement at The Star is the offensive line room. And a guy like Guyton is a centerpiece to a sustainable "youth movement" growing older and better together.
Schottenheimer and the Cowboys Nation see "home run" potential here.
What, when you look at the "before and after'' photos, do you see?
