There has been a little discussion regarding the difficulty (some would say futility) of betting the futures for the KY Derby. According to Haskin, only 2 of the initial 23 horses in the 1st futures bet from November remain as qualified for the KY Derby -- Cairo Prince and Ride on Curlin. Pretty amazing stat. All of course at that time were 2 year olds who have sadly fallen off the trail. Would make a nice and very profitable exacta though.
