Welcome to a change in Cowboys culture. They have on campus a fledgling big-play wide receiver who is not prone to being up all night (Michael Irvin), petulant (Terrell Owens), or a magnet for attention for all the wrong reasons (Dez Bryant).

Welcome to the sedate, by the book, workmanlike world of rookie Terrance Williams, a homegrown talent (W.T. White) tiptoeing in the footsteps of Walt Garrison (Lewisville), Harvey Martin (South Oak Cliff) and Everson Walls (Richardson Berkner).

“He’s a very quiet, serious-minded guy,” Cowboys coach Jason Garrett said the other day when the topic turned to Williams.

“We think that’s actually a really good trait. He’s really locked into meetings, and if you ask him questions, he’s on top of it. It’s important to him. He’s a good notes taker. And I think that has had a lot to do with the success that he’s had.”

There’s more gush from Garrett. But you get the idea.

Williams already has set a Cowboys rookie record by catching touchdown passes in four consecutive games. Through 10 games, he has 29 receptions for 498 yards and five touchdowns. Even with veteran wide receiver Miles Austin scheduled to return Sunday against the New York Giants from a hamstring injury that has sidelined him for five games, Garrett promised Williams would remain a vital cog in the offense.

“We’ll have different personnel groups in the ballgame, and both of those guys will be a big part of the plan,” Garrett said.

Here’s the headline about Williams. He has made himself “a big part” of offenses by attacking football the same way since his days at North Dallas’ Marsh Middle School.

Talk to coach David Bates, who worked with him at Marsh. Or coach Evans at W.T. White. Or coach Briles at Baylor. It’s a one-voice hallelujah chorus.

Most reluctant of all to talk about Terrance Williams is Terrance Williams.

“The simple fact is I have never been one of the fastest people or one of the strongest people, so I always just stuck to my game plan no matter,” Williams said, standing in front of his Valley Ranch locker last week.
