LONDON – Receiver Amari Cooper was targeted on only one throw in the Raiders’ loss to the Chargers on Sunday.
Quarterback Derek Carr said that doesn’t mean he wasn’t looking Cooper’s way.
“When I look at targets, I don’t look at them like I only looked his way one time,” Carr said Friday at the Raiders’ hotel in London. “There were multiple times in the game where my eyes went straight to him, where I’m looking to see if it was going to work or things like that. And it just didn’t.”
Cooper’s usage has varied week-to-week this season. In Weeks 1, 3 and 5, Cooper was thrown to nine total times for four catches and 36 yards. In Weeks 2 and 4 combined, he was targeted 22 times for 18 catches and 244 yards.
Offensive coordinator Greg Olson was asked about that fluctuation and said getting Cooper open is “on all of us, really.”
“Finding ways to get him open and him working to get open,” Olson said. “I think it goes both ways. And there have been teams that have tried to take him away, and we’ve worked on other matchups. It’s a game of matchups. Certainly we like him as a wide receiver and every week we will install plays to take advantage of those matchups with him.”
Cooper on Friday agreed with Carr that targets don’t provide a full picture.
“A lot of times, plays are called that I’m the first read, but the defense doesn’t allow him to throw that particular route,” Cooper said. “So, no, I don’t look at the amount of times that I’m targeted as the amount of times that he’s looking to throw me the ball.
“There’s always a lot of opportunities out there. But like I’ve said, we have a lot of talented receivers, tight ends. So a lot of times, I might be open but two or three guys are open as well.”
Week 5 marked the first time this season the Raiders have not had a 100-yard receiver. Cooper said the Raiders have “a lot of guys who can go off and kind of take over a game,” but he added: “We would like to do it more collectively as a group.”
“I think that would be better,” Cooper said, “and give us the best chance at winning.”
Injuries: Left guard Kelechi Osemele is doubtful for Sunday’s game against Seattle because of a knee injury suffered in Week 4 against Cleveland. Jon Feliciano will again start if Osemele can’t play. … Defensive end Frostee Rucker (neck) is also doubtful. Safety Karl Joseph, who has missed the past two games with a hamstring injury, is questionable.
No “Hard Knocks”: Head coach Jon Gruden was asked if he would consider having the Raiders on HBO’s “Hard Knocks.”
“I don’t think so,” Gruden said. “I think my TV days are over.”
Gruden was also asked to name his favorite James Bond. His answer: Roger Moore.
“I thought Roger Moore was as cool as cool gets,” Gruden said.
