I just think of jersey retirement differently. I think of it as an honor that a franchise bestows on a player, not a right that a player is entitled to based on individual accomplishments. If I'm OKC, I don't honor him for bolting in free agency for the competitor when we were willing to pay him more.
I think of jersey retirement as when a new player comes to a team and wants that number, people think "Oh whoa whoa whoa, you can't be that number. That's so-so's number!" because fans are still attached to the player even after they are gone. They are numbers that it takes zero thought to recall what number they were. I think #34 in Boston, #24 in LA, #21 in Minnesota, #23 in Cleveland, #3 in Miami, #21 in San Antonio (probably #9 and #20 as well), and #41 in Dallas are the few numbers I'd 100% like to see retired from the last decade. I'm picky though. Steve Nash I'd list as questionable since I couldn't recall his number right away.
