Fantastic player as well. Big guard, one of the best defensive players of his time. Those Bulls teams in the late 60s/early 70s were nasty, but couldn't quite get by the great Knicks, Lakers, Celtic, Bullets, Bucks teams of that era. They had Sloan and Norm Van Lier in the backcourt, and Bob Love and Chet Walker at forward, but never had the center play of those other teams.
RIP, Jerry.
