By pro standards Michael Chang had a weak 2nd serve. He just spun it in without a lot of pace. I don't know where you got the idea that he had the best second serve among pros. His average speed on his second serve was 77 mph with 3928 rpm compared with many players averaging...
If I could give more than one thumbs down I would. If the person who posted this video had clearly put chipmunk version in the title it would be ok. The explanation "someone suggested me do this" is weak
