Celtics get JaJuan Johnson from Nets

The Celtics swung a minor deal in the first round of the NBA draft, trading back from 25 to 27 with New Jersey and picking up a 2014 second-round pick in the process. The Celtics wound up with Purdue big man JaJuan Johnson, a rangy 6-foot-10 shot-blocker who averaged over 20 points and 8 rebounds a game for the Boilermakers.

Johnson stayed all four years at Purdue and ended his career with a bevy of awards including Big Ten Player of the Year, Big Ten Defensive Player of the Year and consensus All-America. The Celtics desperately need size and Johnson offers that, along with some upside offensively.

Officially the Celtics selected Providence’s Marshon Brooks with the 25th pick. The trade went through after the Nets chose at 27. A league source indicated that the Celtics would have taken Boston College product Reggie Jackson, but the Thunder took him one spot ahead of their choice at 24.
