Because of the degree of difficulty the first two dunks are way more impressive than the one on Singler, although the one on Singler is still vicious.
Demar on Mozgov is sick. When I first saw that live, I was like WOW. But as it was happening, I could believe Demar was going to finish it.
On the other hand, when I saw Ross going up for his dunk on Faried, I was legitimately shocked that he found a way to get that ball around him and through the hoop. Slow motion replays do an even better job of illustrating how hard it was to get around him. There are some cool posters of that dunk.
Gotta go with Ross for the shock factor.
