No I really hate when kids get illegally coached. The great thing about tennis is that it's just 1 on 1 and you have to get through it all yourself. Coaching during a match can unfairly change the outcome of a match and I have lost because of it. I go through all of my mistakes with my dad after the match and I still learn a lot and it improves my match play.
