The idea of a lottery pick in this year's draft being available in trade talks is a surprising development, but several teams appear amenable to a deal.

"I thought getting a lottery pick via trade would be virtually impossible this year," one NBA GM said. "It's not. There are a lot of teams in the lottery right now that would prefer a proven player. A lot of owners have lost their patience with the rebuilding process."

The Boston Celtics, Los Angeles Lakers, Sacramento Kings, Charlotte Hornets, Minnesota Timberwolves and Phoenix Suns are all open to offers for their lottery picks, according to sources.

The Milwaukee Bucks, Atlanta Hawks, Dallas Mavericks, Portland Trail Blazers and Toronto Raptors are expected to be especially busy looking to move up or to acquire a second pick.
