This is such a great question, that I created - thankyou, please write in better answers!!! I can't remember much from when I was a kid from the 80s/90s, so relying on older guys to come up with some hum dingers.
Note that we should exclude serious injury guys (e.g Brandon Roy, Oden, maybe even Arenas), and players who slowly became less relevant (e.g Udonis Haslem).
I want big ass drops of the cliff.
Carmelo does not yet qualify, because he may bust out, who knows?
