Let me show you how important rebounding is...check this stat out:
In the best of seven conference finals last year, the winner of each game was the team with the most rebounds...all 7 of them. That's why D'Antoni was never able to take them to the big dance while in Phoenix. The system works well if you have a few all-stars, especially an all-star PG (Nash), but if not we should expect nothing more than what we're getting with the talent we have. The main reason we were able to beat Miami yesterday is because Bosh was out and they were lacking a low-post threat. That's who normally kills us by dominating the boards and paint, drawing double-teams and opening up Lebum and D'whistle.
Also, Carmelo Anthony alone isn't going to all of a sudden make D'Antoni's system work. I think he could have 5 all-stars on our team in his system and we still wouldn't win in the Finals. That's how flawed it is. At least our games will be much more entertaining than they have over the last 10 years and maybe we'll finally win a playoff series if we get Carmelo. One can only hope.
