OK, just to get something related to tennis here, I'll ask TCF a question in relation to his 12 year rule.
If a player first started playing competitive tennis as the bottom guy on a high school team in his junior year in high school and played in Spring and Summer. Then he started playing year-round for the first time in his life in the Spring of his Senior year and by the Spring of his Freshman year in college (no longer a junior) could beat the lower-ranked guys on top 20 Division 1 college teams and all the top juniors in the state. What would be his potential?
I would like to know if the 12 year rule is scientific or speculative ?
