Via Gery Woelfel of The Journal Times:
It’s hardly a secret a slew of teams, including several lottery ones, are exploring potential trades. One team that is making a concerted effort to move into the lottery, league sources claim, is Boston. The Celtics are dangling their two No. 1 picks: Nos. 16 and 28.
A couple things: I'm not sure exactly who Woelfel's "league sources" are, but considering he writes for a paper in Racine, Wisconsin, I'd be willing to bet there isn't actually any new information here since the last time we heard similar reports about the C's interest in moving up in the draft.
