Celtics officially acquire David Lee for Chris Babb, Gerald Wallace

The Celtics have scheduled a press conference for 3 pm on Monday, when they are expected to introduce new acquisitions Amir Johnson, Perry Jones and David Lee. Returning free agents Jae Crowder and Jonas Jerebko are also set to make an appearance. As a prelude, on Monday morning the C's officially finalized the trade that brings Lee to Boston from Golden State.

The definitive deal has Boston sending small forwards Chris Babb and Gerald Wallace to the defending champion Warriors in exchange for power forward Lee. The 32-year-old Lee played just 49 games for Golden State in 2014-15, largely because of a hamstring injury, and averaged 7.9 points and 5.2 rebounds in 18.4 minutes per game, his lowest totals since his rookie season.

He does bring a veteran presence to the Celtics, and should have enough in the tank to put up good numbers with increased playing time. While Lee will be an unrestricted free agent next offseason, the Celtics have given up next to nothing in return: Babb spent all of last season in the D-League and Wallace appeared in just 32 games for Boston.

Also on Monday, the C's acquired shooting guard Zoran Dragić, who they will reportedly waive.

As of this writing, Crowder has yet to be officially re-signed, but he has arrived in Boston:
