In the course of researching the big-time sports betting world, I soon discovered there was unanimous agreement among the dozens of people I interviewed (bookies, runners, movers, sportsbook managers, and pro gamblers) as to who the world's most significant and influential sports bettor is and has been for some time - Billy Walters. It has been widely reported that Walters is the "Rick Matthews" featured in Michael Konik's The Smart Money (which I have noted before, and which I reference in Gaming the Game). Anyone interested in the history and sociology of the highest level of sports betting would be wise to start with a look at the man heralded as the head of The Computer Group.
