The guy you're thinking of is Jim Marsh. He's now a coach for a (really good!) Seattle AAU team.
I totally forgot about him. I think he's from the days when they'd show random games on KCPQ, broadcast by Raycom sports or something. I'd be flipping through the channels and whoa--a Sonics home game?
Sorry about the new post. Couldn't figure out how to put a picture in a comment...
