If you don't know who Cory Jefferson is, don't worry. He was a second round pick acquired by the Brooklyn Nets on draft night when they were scooping up second round picks like they were Nic Cage DVDs. As you can see in the video above, he can get off the ground with a quickness.
As you can also see in the video above, Patrick Patterson shouldn't try to jump with him when he's around the rim.
