Afflalo should be used as a post up guy, outside of that a spot up shooter (3 ball mainly). Too many times we give him the ball in the mid-range area - which leads him trying to create something which he simply is not good at. He is reliable to take a good look 2 ways. A spot up 3 from outside (whether he makes it or not, it is a good shot for us) or him posting up inside.
Afflalo leads the team in points per possession for post ups.

In contrast, we should avoid Porzingis in the post even when often the mismatch is glaring, and try to get him more looks from outside or on the move. We want to get Porzingis the ball when he's on the move or spotting up. He's our worst scorer in post ups. Porzingis still has major advantage in shooting over guys much smaller over him on the move. We don't have to post him up to take advantage of that. He isn't ready in that area of the game. His post game needs a year or two to hone. Porzingis shoots 1.1/3.2 on three pointers which the equivalent of scoring at over 50 percent in the post. His post FG percentage is actually very low - in the 30's. People complain about his 3 ball, but look at Curry/Thompson. You want natural gifted shooters like Porzingis to be that rare player who has the green light to "get them up" from outside. Any time Porzingis has a look as a jumpshot he should take it.
In a way we miss Calderon on offense. He was smart in directing and organizing the offense. I think the team's record with Lopez/Porzingis/Melo/Afflalo/Calderon all healthy and playing is quite good - of a playoff team. Ever since Melo rolled his ankle, it's just been one thing after another with this team and our playoff hopes have gone down the tubes with it.
I'm not upset with Afflalo, he's given his best and done what he can. The team doesn't have the depth to deal with injuries to their veteran/top 5 players. Since Melo has rolled his ankle, I believe we've had 3 games where the top 5 players on the team have been available. Have gone 2-1 in that stretch. If we don't have these guys the rest of the way, I can't see us even finishing at .500 (41 wins). We need Afflalo, Jose, Melo, KP and Lopez to be healthy the rest of the way.
