IRVING, Texas (AP)—Tyron Smith is so young he doesn’t turn 21 until nearly Christmas.
Bill Nagy is so unproven he didn’t even start every game at Wisconsin last season.
Phil Costa’s body of work as an NFL lineman includes two games last year and two this preseason before hurting a knee.
Yet those guys are three-fifths of the Dallas Cowboys’ offensive line that will protect Tony Romo in the opener Sunday night, a game that also marks his first real action since breaking a collarbone last October.
Romo said Monday he believes the youngsters have done a good job of getting ready to take on the Jets. He said he’s confident the linemen will “work hard and give it their all out there, and that’s all you can ask.”
