IMO, i think its dumb. Might be thinking extremes here but going up for essentially no bearing on the game might even cause a jammed finger or sprained ankle, leg. I'm even thinking that the ref might get annoyed and actually give the offensive player continuation and charge the opponent goal tending. extremes, but who knows.
definitely not strategic coz i dont think it has any effect on the game. definitely not intimidation coz youre essentially preventing a shot that has already been written off.
