• Rule No. 1: These 30-team rankings are only for offseason moves, the things teams have done since they last played a game, taking into account the Draft, free agency and trades. It is not a predicted order of finish for next season; I do not expect Sacramento, for example, to have a better record than the Bulls, nor do I think Charlotte now has a better team than Miami. It's relative.
• Rule No. 2: This is as much art as science, weighing the impact both of the Draft and free agency, but also assessing whether teams got value in their free-agent signings. Overpaying the right player is as much a sin as signing the wrong player. New coaches, new GMs, new owners and new arenas are also significant factors in judging a team's summer success, for a good coach can coax some more wins out of a roster, and a new building can generate the kind of revenue necessary to let a team be aggressive in pursuing free agents and trades -- if not this season, then in future seasons. Also, teams that are rebuilding obviously have different priorities than teams making a championship push. That's factored in.
• Rule No. 3: Continuity matters here as well. The most successful teams identify a core group of players and keep them together several seasons; teams that re-sign their own players (at reasonable amounts) get good marks from me. The bottom line, though, is how much better is a team after its offseason moves than it was before? That is what is being ranked here: improvement.
• Rule No. 4: With more and more teams terrified of paying luxury tax, a team that stands pat much be viewed in the context of preserving cap space and/or flexibility in order to be able to make unbalanced trades down the road. Was Atlanta wrong not to blow all its cap space this summer, once it was clear that neither Dwight Howard nor Chris Paul would go there? I had to make a judgment on that. Same with Dallas, which obviously had other, bigger plans than what the Mavericks wound up doing.
