After last week's disclosure that Boston was trying very hard to get Iverson, it's likely that Billy King got a lot of calls in the last few days, and it may take a while to sift through all the new offers. And while the best guess for now is that the Celtics remain the leader to land Iverson (and, yes, it would make sense for Philly to get Delonte West in a potential deal), other teams like Golden State and Denver with a surplus of players and a willingness to deal could still cut in front.
For example, the Sixers dearly covet Warriors forward Troy Murphy, who seems to be on the trading block; a package with a couple of other Warriors might get things done.
