AJ isn't very memorable outside of the Spurs fandom. For me, it's clear he got his jersey thanks to a certain shot along the baseline in '99. This was a legendary event in San Antonio history, like, the actual city was forever changed (from a cultural standpoint). If you are native of SA and were alive at the time, there's no way you didn't know about it, no matter if you were a fan of the Spurs or not. The only bigger shot in that entire run was the MDM.
Bruce Bowen though was a major contributor for three les. He was stiffed a DPOY or few as well. I admit he sucks balls on paper which is why it might be confusing for someone who didn't watch the Spurs back then.
