Cowboys' Terrance Williams coming on

Tim MacMahon checks in from Oxnard on Dallas Cowboys rookie receiver Terrance Williams, a third-round pick who could make an impact as early as this year as a deep threat for Tony Romo. Tim writes that Williams "stumbled out of the blocks" but has "flashed his playmaking potential in recent days."

There’s no question that the 6-foot-2, 200-pound Williams has the ability to be a deep threat. He led the nation with 1,832 yards as a Baylor senior, averaging 18.9 yards per catch. He’s provided glimpses of his ball skills and ability to get deep during camp.

The challenge for Williams, who should see a ton of single coverage as the Cowboys’ third receiver, is getting off the line of scrimmage against cornerbacks who are stronger, smarter, faster and tougher than the dudes he torched in the Big 12.

The Cowboys don't need Williams to be a starting wide receiver for them this year. They have two excellent starters in Dez Bryant and Miles Austin, a top receiving tight end in Jason Witten, and they like what Dwayne Harris showed last year in the No. 3 wide receiver role. They could give Williams time to develop if he needs it.

But he's a guy they drafted because they liked his talent, and if he develops quickly in camp and the preseason, he could earn more playing time than they maybe anticipated him getting as a rookie. That would be a positive development for the Cowboys' offense, even if Bryant and Austin are fully healthy all year.
