Amare, Felton, and one or more of Chandler/Gallo/Fields would be the overall players better than Melo if he came.
I'm assuming he meant their games, or skill sets, are more diverse and rounded than Melos. Which may be true, but a lot of bench players n backups would also be superior in this way. Don't think it means that all them actually impact the game or their teams in a more impactful/ better way.
If that were the case itd be declaring trading any of them straight up for Melo wouldn't be worth it.
