The first dunk, Zo got piece of, but Carter got it thru anyway. They were pretty much facing each other on the baseline.
The 2nd one, Carter got a good open area of paint to take off from. He jumped into Zo's chest with his left shoulder and cocked the ball out of Zo's reach in his right hand. He dunked it right-handed with ease. I use the Dr. J example because Carter is the only guy who comes close to Dr. J as far as cocking the ball so far away from his body. No matter who you were, if you tried to challenge Erving without hacking him, you were going to get a facial, no ifs, ands, or buts.
