I think it's too soon to tell on most, but AD is the clear #1. Towns will probably be second. Rose is the only MVP, but his prime is also probably the shortest. Bennett was a bust, Simmons should be solid, Wiggins is good. Blake is close the top when healthy, but he's missed a lot of games over the years.
I do think Fultz will be better than Kyrie. Maybe it's my green shades, but I feel his size and underrated athleticism will possibly make him as good/better than Irving AND Wall.
