Some Raiders fans have noticed how diplomatic Jon Gruden is in everything he says or does concerning the Oakland Raiders, and this provides some measure of hope he would consider returning as head coach.

Well, that’s not going to happen so long as Al Davis is alive.  Al is first of all threatened by Gruden’s popularity.  In Al’s world, no one is allowed to take any credit for the team’s (potential) success more than he is.  Al is a very smart guy but he’s also completely absorbed in his own megalomania.
