Add David Robinson, much like Tim Duncan, to the underpriced list. He was a beast on the court and a great man off of it as well, serving in the Navy. A quiet, but fierce, leader. I always respect players who leave it on the court and let their game do the talking. You can still pick up his stuff at reasonable prices! He benefited from being injured, the Spurs stealing the #1 pick from the Celtics (Duncan) and getting a dynasty out of it. Love chunky game-used patch pieces like this.
