in my opinion, the big difference is experience and preparation. i have always thought JR has as much talent as anyone, and i think by the time he is his in his mid 40's, he will hold every jock record out there. i love watching the guy ride, especially on speed tracks like GP. since his record setting performance at Sar last year, however, it's getting tougher to make money betting on him. i made a big double bet on fla derby day with JR in the first two legs, thinking i was getting $6.60 back, which i though was fair. the double returned $4.40 for $2 !!!!!
