There are 2 teams we've got to worry about, Miami and Chicago.
Chicago is going to be severely hamstrung by Boozer's contract which goes for 4 more years. Whatever the new cap situation is, they have Boozer, Deng, Noah tied up long term for 41 million after next season. Add Rose, who'll be in that range or likely higher depending on the new CBA. Thats it for them. If Rose makes lets say 13 million which is a low number for a former MVP, They will be at 54 Million for 4 players, only one is a star and the others are role players of varying levels. They will have a problem adding talent except through the draft, and they will not have high draft picks. CBA will determine if they have LLE, MLE, or any other money to play with. BUt they have little room for improvement.
Miami after next season will have 71 million tied up with the big 3, Mike Miller, Udonis Haslem, & Joel Anthony. Mike Miller & Haslem are 31. They'll be locked in for another season bringing them to 76 million. Whatever the cap is, they are way way over it. The team will be severaly limited in its ability to get things done outside of the draft where they again will not pick high.
Knicks have space after next year with only AMare, Melo, Balkman & Toney Douglas committed for 41 million. Thats at least 13 million less than CHi and a full gazillion less than Miami. We have ample opportunity to improve. Next season isn't necessarily about winning a championship. We should be one of the top 3 teams in the east next season. It should be about developing our draft pick (Selby?Brooks?) and developing Jerome Jordan. It will also be about seeing what MDA and his defensive coordinator can do with our stars and replacing him if we don't get it done. Finishing with a high seed will mean we make it at least to the 2nd round with a chance to advance past that and a possibility of getting to the NBA Finals.
After that we have the FA summer of Paul & Howard. But we don't even need them necessarily. We just need to build solidly on this foundation that we have. Jerome Jordan was our iron in the oven. We need to buy a 2nd rounder and draft a big (Keith Benson, Greg SMith, etc) and put another iron in the oven. Next year should be a good year for us and truly the sky is the limit. The year after should be our year if we do it right.
