FLORHAM PARK, N.J. -- If DeSean Jackson is on the field, fine. If not, so be it, Darrelle Revis said.

"I don't care if he plays or not," the Jets' cornerback said of the Redskins receiver, who has been sidelined for more than a month by a strained hamstring. "It's about us as a team."

Jackson, who led the NFL with 20.9 yards per catch last season, made headlines in August when he said, "I don't feel no one can stop me" -- including Revis. But Revis took the high road, saying: "He's an explosive player. He makes plays."

Redskins coach Jay Gruden said on a conference call that he's "optimistic" Jackson will play despite being limited in practice on Wednesday. "He loves to compete against the best and Darrelle is the best, so he'll do what he can to get out there," Gruden said. "But he also knows that we have a lot more football to play."

Williams backs USC

Leonard Williams wore a USC T-shirt to show support for his embattled former team. “Even at a time like this is when I’ve got to represent most,” the first-round draft pick said.

USC athletic director Pat Haden fired coach Steve Sarkisian this week amid reports of a drinking problem. “We’ve been going through a lot of hard times at SC, even while I was there, coaching changes, all that type of stuff,” Williams said. “I feel bad for the players.”
