Got better:
Philadelphia - The additions of Webber and Rogers were good additions considering
what they gave up, and the got another ending deal to make for trading one away.
Golden State - In terms of talent they got better. Dale Davis is a worthless stiff, and Speedy Claxton is far from Baron Davis quality. Biggest issue is GS has spent a ton on a worthless big guy (Foyle), and a ton on a injury prone PG. If Baron Davis has back problems, this team will suck for another 5 years.
San Antonio - Mohommad is as decent, and IMO much better than Rasho
Dallas - I am not a fan of Van Horn, but he is much better than what they gave up, which was nothing
Boston - Payton is a shell of his former self. Antoine Walker is horribly overrated, but they are a little better, with him than Payton. Losing Welsch may be a mistake long term, but they weren't using him anyway.
Stayed the same:
Denver
Atlanta
Got worse:
New York - Isaiah Thomas is a moron
New Orleans - They detonated a bomb, and are starting over
Milwaukee - They just moved an expiring contract a year sooner. They better hope they resign Redd, and a couple of other FA or this was a very bad decision
Didn't do enough to make a real difference
Houston
Miami
Cleveland
Charlotte
To be determined
Sacramento - I think this was not as bad as many think. Sacramento moved their biggest albatross, and have changed their focus. Long term I think we could look back and say, this wasn't so bad after all.
