LOL, 98% of the horses are on steroids, and there is probably less drugs in horseracing than the NBA.
Once again, the hype machine gets us all built up for a letdown. Big Brown "great?" Because he was undefeated in 5...5(!?!) races? Here's greatness: YouTube - Secretariat's Triple Crown - Part 2 - Belmont Stakes
so, no physical problems with a horse that shouldve blown away the field. its the only horse to win the first two legs by 4 strides or more and not win the third---and it came in last. what are the chances that the fix was in?
Zero. The horse was worth more to EVERYONE involved if he won. There is no such thing as a sure thing --- especially in horse racing.
