An NBA source said agent David Falk has called the Nuggets numerous times about several sign-and-trade proposals for his client, Nuggets forward Juwan Howard.

Thus far, the Nuggets have balked at all the potential deals since they don't want to affect their salary cap space. Denver would likely have to acquire a marquee player for such a deal to work. One sign-and-trade deal included Howard to the Detroit Pistons for forward Corliss Williamson, point guard Chucky Atkins and center Ratko Vardo. The other was with the Orlando Magic that included point guard Darrell Armstrong.

Falk and Howard could not be reached for comment.

In other news, Agent Calvin Andrews said Nuggets rookie forward Carmelo Anthony is expected to sign his contract today.
