I believe Michael Jordan is partly to "blame". When you have someone challenging for GOAT status saying he's chasing that ghost in Chicago...well that ghost retired years ago. Even though baseball is, imo, kind of stuck in the past as a sport, basketball, imo, is kind of stuck in the past on its players. When we discuss top players in the NBA, Jordan, Magic, Bird, Jabbar, Russell, Chamberlain, etc come up--but when we put Lebron in that mix, we're again reminded that a lot of those players are from way back when (and NO, I'm not saying that's my list--that's what I often hear).
Brady, Rodgers, Mahomes--recent. Nadal, Djokovic, Federer--recent. Trout and Ohtani--current. But yes, basketball ghosts keep entering the discussion and seem to keep basketball linked to the past (and no, I'm not saying it's the only sport that does it--just saying it tends to happen).
