I'm so glad you brought that up, by all accounts I remember Carmelo was a terrific team player w/ the olympic teams. There is no player in the universe who can win w/o teamates and melo has been saddled by this his entire career, great player trying to do too much.I forgot to mention his fine Olympic career, which only strengthens his case. And I was also considering some of the small forward/scoring power forwards already in the HoF, many of whom are not his equal, IMO.
As for his ultimate place in history, he probably doesn't belong among the top 10 small forwards right now, but if he does play at a high level into his late 30s and get himself a title, he could possibly crack the list.
