Several members of the media, including Adam Schefter of NFL Network and Albert Breer of the Dallas Morning News, have noticed an intriguing fact regarding the behavior of Raiders coach Lane Kiffin at the Senior Bowl in Mobile, Alabama.

Or, specifically, his attire.

While all members of the Raiders staff coaching at the Senior Bowl are wearing Raiders gear, Kiffin is merely wearing black, with no team logos or names.  Per Schefter, Kiffin has been doing it all week.

Publicly, Kiffin denies that there is any trouble brewing between himself and management.  Ditto for the team.  However, there are multiple reports that owner Al Davis has asked Kiffin to resign.

UPDATE:  Several readers have pointed out to us that 49ers coach Mike Nolan is dressed in the same way as Kiffin, with no team name or logo on his outfit.  We didn’t notice, because we can’t bring ourselves to watch college all-star games.
