Playing UTR tournaments has made me realize something. Its not uncommon to see a 12-13 year old kid playing at 6-7 UTR (4.0-4.5 level) level. They practice somewhere around 3 times a week and they probably started around 7-8 years old. Its also not uncommon to see 4.0 - 4.5 player who plays 3 times a week but has been playing at the same level for about a decade. Now I understand declining neuroplasticity and bad knees are an issue but the gap is just enormous. Is it the coaching? Is it that they spend more time drilling vs match play? I'm guessing its all of the above but is there anything we learn to get better faster?
