Khalil Mack has had an excellent rookie season in what has been a disappointing 2014 for the Oakland Raiders in terms of wins and losses.

The Raiders play at the Seattle Seahawks on Sunday.

"I think he's really good," said Pete Carroll. "He jumps off the film. Every one of our coaches, when they break up and start looking at the Raiders and taking seriously what they're doing well, everybody comes back talking about him. He's almost unblockable and he's got a great motor. He's fast, he's tough, he's instinctive. We think he's an obvious factor."

Brian Hoyer last week said Mack was "one of the best players we've gone against this year, and that's a unanimous decision in the locker room."
