Touching ankle during the follow through

my coach told me to do this when following through. is this a good way to follw through?

I think that the wrist should come to the opposite knee, maybe a little below but not much.

Your arm is going to go where it goes.

this is perfectly understandable and clear lol

but true its something you shouldnt force just make sure you dont stop it… (like rich harden)

Good comments above. I’ll just add that where you finish is largely the result of your arm slot. No way a side-armer (like Randy Johnson) is gonna’ finish down by his ankle.
