I know it sounds crazy now but Capriati was undoubtably the best 15 year old tennis player in history. She should have won the 91 U.S Open, which she choked twice serving for her semifinal vs Seles, and Navratilova herself admits Capriati would have beaten her in the final had she won that. She would have been the only 15 year old in tennis history to win a slam. Capriati is probably also the best 13 year old player ever (Worlds #1 junior at 13) and 14 year old player (slam semifinalist at 14) evert. So based on that had she been managed properly and fulfilled her massive potential did she even have potential to become the best ever. After 1991 she got off track IMO. Even though she remained top 10 in 92 and 93, she did not improve on her 1991 level of tennis which for someone that young is crazy. Her burnout and subsequent retirement for awhile could have been seen alot sooner than it did. She did come back in the early 2000s and against all odds won 3 majors, and solidified herself one of the minor greats of her era and a future HOF. Those 3 majors were even a bit lucky as there were probably 6 or 7 people better than her even those years in tennis ability (she regularly lost to Venus, Serena, Mauresmo, Davenport, Henin, Clijsters even those years), but she did well to catch some lucky breaks and peak at the right times. Still by then it was far too late for her to come anywhere near her once held potential. Had she had better people managing her and bringing her up, and had she fulfilled all the potential she showed at 13-15 could she have been the female GOAT though.
