D'Antoni and Melo can't co-habitate.
The dude's gotta get some isolation because, frankly, he is what he is: a successful 1 on 1 player. He's had a season to forget thus far: statistical nightmare compared to other seasons. Carmelo's down in every category except assists where he is up, but that will decline with Lin and Davis' presences. But he has to be given some opportunity to play his game by design.
Melo and Mike will never fit within one another's modus operandi. EVER. It's an absolute New York conundrum.
But in the absolute favor of D'Antoni, we've seen how successful this team can be with Melo's absence, and not the other way around.
That has also been the case in Melo's presence, however, as the second unit's +/- rating exceeds that of the starting lineups'. That doesn't correlate directly to Carmelo or any other individual, but this team can play Mike's game and win/do better than the starters because they're a better fit and play defense as a unit and as individuals better than a line up with Anthony in it.
It's an absolute mess.
Melo's having a shit season, but Mike gives him nothing in the form of a play(s) that's set specifically for Carmelo to get him in rhythm, never mind to take advantage of a situational mismatch etc. That doesn't excuse the horrible shooting, missed layups, techs/ejections, and general poor attitude, however....... - that's a personal observation.
I think thus far Amar'e, D'Antoni and Carmelo can all be labelled as individuals that are underachieving (or even failing) at their positions, because they just can't figure this shit out, nor seem to find any method in which they can optimize one another's or add to the other's role(s) for the betterment of the team.
I'd love to see how they communicate together off the court, and if there's a sense of alpha presence for D'Antoni as there should be. He is the coach after all.
If this season ends in tragedy - there's no guarantee we'll make the playoffs whatsoever - Mike will be the one that gets the ass, however, and we'll see what the outcome is of that.
