While that may be true, Bob was probably the most under-rated of the three. Swindon's Number one for four years, he led the Robins to the National League title in 1957 with an average of around 10.5, and the only riders to score more points during the season were Briggs, Craven, and Peter Moore.
Also, we can't forget him winning the Christmas Vase at Wimbledon on Boxing Day 1956, ahead of such riders as Nigel Boocock, Peter Moore, Ron How, and his brother Cyril.
