Take a look at Maya's record:
en.wikipedia.org
She won AAU, high school, college, WNBA, Chinese League, Spanish League, Euro League, World Cup, and Olympic championships. In 16 years, she won a major championship almost every year.
In the context of UConn's experience over the past 3 seasons, note that Maya missed 1 game (for precautionary reasons) in 16 years. She was the Lou Gehrig/Cal Ripken of basketball.
UConn has had 6 undefeated seasons. Three other teams have had undefeated seasons. The ONLY team to have consecutive undefeated seasons was UConn in 2008-09 and 2009-10, led by Maya Moore and Tina Charles.
