Veteran tight end Chris Cooley says quarterback Robert Griffin III is only the second Washington Redskins rookie he has seen arrive in the NFL and immediately carry himself with the confidence and demeanor of an established player.

The other, Cooley said, was the team’s late safety, Sean Taylor.

Cooley also said of Griffin: “I never see doubt in that kid’s mind.”

Griffin’s ever-growing celebrity continues to be noteworthy. After the Redskins arrived back at Dulles Airport following last week’s preseason-opening triumph at Buffalo, Cooley said, the players turned on a television—and in short order saw two commercials featuring Griffin.

“He’s everywhere,” Cooley said.
