Active wrist usage is a requirement to counter the rotational force created as the racquet rotates around the hand....Much of wrist movement is for proper racquet face orientation and for directional/shot line purposes.
Thanks to JY, two months I was the member of the tennisplayer.net and drown in his absolutely incredible video library. There is too much information to consume for old man.
Active wrist usage can also contribute more than 50% to RHS. Monfils regularly hits 120 mph FH, but Fish cannot due to his passive wrist.
