I think a coach like Thibs would do better with a team with Melo/Rose and a coach like Horny would do better with Minnesota's roster. Or lets put it this way if we traded Rose/Melo for Rubio/Wiggins BOTH teams have better season's. Thibs knows how to use talent like Melo/Rose better on defense and get them to play simplistic ball on offense. Thibs is a good coach for talent like that, but as you see in Minneosta, he is not exactly a good coach for a young team that needs to develop.
It comes down to this for me. I think Hornachek has not done a good enough job this year. When a team with this much talent fails to even play .500 ball, it is on both the star players AND coaching. You can't put it on young stars like KP as they are learning and you can't put it on role players as they are not high usage players. This season has been bad not because of Phil, but because the combination of Horny/Rose/Melo never worked out.
Horny works well with KP. He works well with the 2nd unit. As we saw in the Magic game, Horny when he has young athletic players both sides of the ball looks better. Forget the wins and losses, just how we play. The best thing I like about Horny is that he makes the Triangle look modern. Very hard to do that but he has. Fisher made the Triangle look outdated. Not with Horny.
The thing I don't like about Hornachek, is he reminds me too much of D'Antoni. Works well with young point guards, young athletic team. Doesn't mesh with veteran star players. Not really a leader.
If we're rebuilding after this season, as in trading Melo, then we must stick with Horny. I think he will be great for a young team. He'll be great for KP's development. Already talking about KP's shot arc, that it needs more arc. On the flip, if Melo is staying, if we're going to go after an established veteran guard in free agency to replace Rose, I think we should probably change coaches.
Since I am in the camp that thinks Melo's time in NY has long expired, I hope we trade Melo and keep Hornachek another year. We need to draft well this summer, we need to get a young player for Melo (even Austin Rivers, future first and capspace will do) ad we need to sign young players in free agency. If we do this, we'll be happy where we are a year from now.
If we remove Horny, keep Melo, replace Rose with a more fitting veteran free agent point, we may make the playoffs next year as an 7th seed, but it won't really get us anywhere longterm IMO.
