Well pacy can answer for himself but Wasim doesn't even understand how and why the ball swings, why certain styles, techniques and conditions produce the results that they do. One example, according to him the ball reverses because one side is heavier than the other, if weight would produce horizontal motion then a ball placed on the table would keep moving sideways. Coaching isn't about telling a player do this and that and you will get this and that. You have to know how to teach and every student is different, you need to have proper knowledge first in order to relay it effectively. Then there is the analysis part of the game, do you think Wasim can break down a young student's action and explain where he is losing pace, what are the points of stress on his body and what possible adjustments he can make to avoid injury and add pace?
