While I would like to RJ to be Bret Stiles, there's one thing throwing me off about that, and it was the same reason I dismissed McAllister.  The psychiatric notes described RJ as "middle-aged".  While I might cut a little slack to someone terming McAllister middle-aged, Malcolm McDowell is 70 years old.  He's not ancient, but I can't imagine anyone in their right mind would consider 70 "middle-aged".

Also going back to Ray, the blood on the wall said "He is man".  At the time of the episode airing, I joked around that it really said "Heisman" and O.J. Simpson was the murderer.  But Ray has what looks like a Heisman trophy in his office so I'm wondering if I may have been correct in reading "Heisman" all those years ago.
