Raiders voice Greg Papa said during the season that there were personalities in Jack Del Rio’s locker room that were having a negative impact on the team.

Two names that Papa brought up were Marshawn Lynch and Michael Crabtree.

“I don’t know if [Del Rio] lost the locker room, I think the locker room just changed. I think Marshawn Lynch changed it and I think Marshawn, being around him for a year, I think it’s time he either retires or moves on to a different team… I just don’t see Marshawn Lynch and Jon Gruden co-existing.”

Overlooked several weeks ago (over here at least) was another name Papa threw into the mix: Jared Cook.

“I think the culture of the locker room was different this year and when I point to it, I think that bringing in Marshawn Lynch and Jared Cook, and more so Marshawn, but also Cook to a lesser extent.”

Cook’s name comes as a bit of a surprise because there were no obvious examples of the Raiders tight end hurting the team with his attitude or work ethic.

Like the many other rumors trickling out of the Raiders locker room, take this one, too, with a grain of salt.
