Michael Jordan definitely didn't have this mindset, and he was the greatest of all time. He was the epitome of cut throat.
The only sports that have seen their best players already are Baseball and Cycling, because they’ve gotten good at catching steroid users.
Basketball isn't really a 5 on 5 sport with this rule. It's a 2 on 2 or a 3 on 3.
I remember in 2004, my brother's coach gave him a VHS collection of 60s and 70s NBA games because "that's when the US played team basketball, that's how I want you to play". I think he also gave him the spurs games of that year and a couple of eurobasket DVDs.
