Is Al Harrington sending out hints?

Al Harrington took to his Twitter feed Tuesday night to give a shout out to Dallas: "Dallas what's popping. Building a nice team over there!" Harrington tweeted.

The Dallas Mavericks have offered the veteran power forward the full mid-level exception starting next season, but he is also being wooed by the Denver Nuggets, who can also offer the MLE, and the New Jersey Nets, the lone NBA team standing with remaining cap space, meaning they can offer Harrington the most of the three clubs.

Denver would seem to be the logical choice for the 6-foot-8 Harrington because of Kenyon Martin's injury history. In Dallas, Harrington would back up Dirk Nowitzki, who, even in an attempt to reduce his minutes, is likely to log 35 minutes a game.

Mavs vice president of basketball operations Donnie Nelson on Tuesday referred to Harrington as a "strong consideration."

Harrington is in Las Vegas where Nelson and Mavs owner Mark Cuban have been camped out for Summer League.
