A potential sign-and-trade between the Raptors and Mavericks involving Shawn Marion appears to have reached a standstill.

The deal is stuck on two points, according to the Dallas Morning News.

An Eastern Conference executive said that one of the points is the inclusion of Toronto point guard Marcus Banks in the deal.

However, Banks is due $9 million over the next two seasons, which would impact the Mavericks' ability to pursue stars in next summer's free agent market.

The other problem is that Toronto doesn't want to take back any salary in exchange for Marion, who is an unrestricted free agent.

If the Raptors won't agree to take Jerry Stackhouse, who has a $7 million contract with $2 million in guarantees, then a third team would have to be found to facilitate the deal.
