A few others to consider
Sugar Ray Robinson - Boxing ( IMHO above Ali)
Heather Mckay - Squash - didn't she win world championships ELEVEN times?
Shelley Taylor Smith - Long Distance Swimming.
Johnny Wilkinson - Rugby.
Betty Cuthbert - Track - four Olympic Golds from spanning 1956 - 1964.
Be interesting to see how the new Chess/ Boxing combo sport takes off! A
