Marbury
Marbury has certainly slimmed down and appears to be in great shape. No one can reasonably deny his physical abilities. On pure individual talent he is several levels above Duhon. However, at best, he is with the Knicks for one year. Resigning him to a new contract at the amount and duration he would likely demand would greatly inhibit the opportunity for 2010 cap space. He is not part of the rebuilding process.
If there is a problem having him this year, the problem is the extent to which his fellow players can live with him. We all hear stories, but none of us knows what really goes on in the locker room. If he can make peace with his team mates, then I am all for keeping him. Perhaps his good play will produce value at the trading deadline.
However, though the Knicks have to pay him, they don't have to play him. As i have noted before, Dolan can play haard ball and things could get ugly. Perhaps the best for all involved is a reasonable buy out. Marbury should be able to make up any difference in the discount with his new team. That team would not have to sign him at the veteran's minimum.
