Yes, he absolutely is. He's simply not putting forth the effort--and playing for a crappy Raiders team, who would? Even if he did his best, his QB can't get him the ball. Remember the first couple of games this season, when Moss was berating Brooks on the sidelines? We aren't seeing that anymore, because Moss doesn't care about this season anymore. Put him on a team that can get him the ball and Moss will produce.
There is no team in the NFL that will take Moss's contract. Al Davis is his last sucker.
No need to take a guy who can't even get himself motivated to play a hated rival like KC.
I certainly hope I am wrong.
