So many great names there. You can make an argument for most of them. Tough to narrow it down to four. I never saw Keith Waples in his prime, but I did see Shelly Goudreau throughout the at the end of the 70's and into the 80's (before he died in 82). I never saw Joe O'Brien, but I know plenty of people who did, and they have more than qualified opinions, and I respect them. While some may make an argument, my friend George Sholty was truly great. Many great, great horsemen consider Mike Lachance as the greatest all-around horseman. You can make an argument for all of these men, and plenty more.
