I think you're twisting some of the age stuff a lil bit.
MJ was 32 when they won 72. He just came in off a 17 game season, switching back to full time Basketball.
He wasn't all that far past his athletic prime at all. A few years later, THAT was past his prime.
Bron, is past his prime. Unequivocally. And we might give him a 3 year deal + trade draft picks clear into 2032.
