http://sports.yahoo.com/nba/news?slug=fanball-raptorsdavisontheblo&prov=fanball&type=lgns Raptors: Davis on the block by Fanball Staff - Fanball.com Wednesday, September 17, 2003 News The Toronto Star is reporting that the trade talk swirling around the Raptors, Blazers and Nets is dead. However, the Raptors are still believed to be shopping Antonio Davis. The Star lists the Mavs and Rockets among the teams still interested in Davis, who has $37 million left on his contract. Views If The Star's report is legit, then you can forget about Kenyon Martin going to Portland and Rasheed Wallace coming to New Jersey. Davis is still a player and whomever gets him will be real happy, because the Raptors just want to dump that salary.
