The 2003 and 2004 championships were hardly single handed efforts. Please, do not insult Ms Taurasi's teammates. Maria Conlon, the only non pro, was almost flawless in the playoffs both years. In 2003, she had one turnover against Texas in the national semifinal and no, nada, zero turnovers in 39 minutes against Tennessee in the national championship game. The following year, Conlon was every bit as good with 1 turnover in 33 minutes in the championship game. The rest of the roster all signed WNBA contracts at the ends of their respective UConn careers; Ashley Battle, Jessica Moore, Willnet Crockett, Barbara Turner, and Ann Strother; All pros. Texas Tech in 1993 was not nearly as loaded with talent.
What separates Swoopes from all the other GOAT candidates, at this point, is that she excelled at both ends of the floor.
You are right about George Mikan though. A giant way ahead of his time size wise, but really not a very good basketball player. At 7 foot, he could not even get high enough to dunk. Had he caught Ray Meyer at the end of his coaching career, he might have been a much different/better ballplayer.
