This was expected, but still very exciting. I have slight doubts about his creativity, but with Griffin, you're due to most likely see something amazing almost every time.
What's even more impressive, is that he's most likely going to be voted into the All Star game (how many rookies make the All-Star team their first year?). With Yao out, and depending on how Dirk's injury plays out, we might see even more play from him.
