ESPN's Marc Stein is reporting that the Grizzlies are close to acquiring Philadelphia 76ers forward/center Marreese Speights in a three-team trade with the Sixers and the New Orleans Hornets. The deal would apparently send second-year swingman Xavier Henry to New Orleans and a potential second-round pick in next summer's draft to Philadelphia for Speights.
Adding a rotation-quality big man without giving up anyone in the team's current rotation would be a good get for the Grizzlies right now and the deal would presumably make it much more likely that the Grizzlies would keep O.J. Mayo for the remainder of the season.
More on this if and when it becomes official.
