According to league sources, only the first two years of the deal are guaranteed. The last two years of the contract are team options.
Mickey's deal makes him the highest-paid rookie second-round pick in NBA history. In eight games, the LSU power forward averaged 12.2 points, 8 rebounds, and 2.4 blocks in 28 minutes.
The Celtics selected Mickey in the second round of the draft for his defense in the paint, but proved this summer that he can also score. He led the NCAA in blocked shots last year, but impressed the Celtics with his rebounding abilities throughout summer league play.
"I think Jordan is a versatile athlete from a defensive standpoint," Celtics coach Brad Stevens said on draft night. "He can guard 4's. He can switch a little bit. He's a great shot-blocker when you look at his numbers for a smaller guy in height, but then you look at his length and his reach, and he's really, really long, and gets off the floor extremely quickly. He's one of those guys that probably shoots to about 16 to 17 feet right now, but can impact the game in a lot of different ways. Another good worker."Mickey is the first rookie the Celtics have officially signed to a deal. First round picks Terry Rozier and R.J. Hunter have yet to sign, as well as second-round pick Marcus Thornton.
Mickey joins a crowded Celtics frontcourt that includes Amir Johnson, David Lee, Jared Sullinger, Tyler Zeller, Kelly Olynyk, Jae Crowder, Jonas Jerebko, and Perry Jones.
