I guess this is just Nate being Nate. Nate Robinson continues to keep Celtics practices loose, posting on his Twitter account this video of him dunking on Shaquille O’Neal. He also gave us footage of him walking in Shaq’s shoes and a Kendrick Perkins/Shaq dance-off. I don’t know about you, but Perk looks pretty nimble here. Also, Paul Pierce posted a video of Nate trying to guard Delonte West in Shaq’s shoes.
