Walton has stated many times on some documentaries and Celtics specials that growing up in SoCal, he was actually a Celtics fan because his idol was Bill Russell. He also refers to himself as a "Celtic" despite only playing with the team for one season. He admires this franchise. Lately, people dont think that because his son is on LA, but what the hell is he supposed to do? Root against his own son because his favorite player was Bill Russell growing up?
And, "so glad we didn't retire his number?" Dude, I don't think there was ever a debate his jersey was getting retired. In fact, that was something that was pushed around 88 and 89 by RAPID Walton fans in Boston. When we got Walton in 86, he was the second most popular player on the team. In fact, his popularity was another spark to the "Boston is a racist town" because he was a bench player (albeit a GREAT one) but was as popular as any athlete in Boston. The guy was loved. But there was never a serious debate the Celtics would retire his jersey. My God, I actually can't believe I'm talking about it. The guy basically put together one healthy season in Boston.
And even so, that's telling. Here's something that just about sums it up. I believe this was written in 2004 too, when the Celtics were the pits:
"All I ever wanted in life was to be a Boston Celtic. Everything else that I ever tried has been terribly depressing and a major disappointment."
