I think The Kentucky Derby is an exciting race. Many don't understand horse racing, but the true fans follow racing all year long. From the stake races that lead us on the Road to the Roses (Kentucky Derby) or Triple Crown, to the road to the best in the world the Breeder's Cup where it all begins again. With experience comes the learning to expect the unexpected always. I've learned that the "best", most talented, favorite race horse doesn't always win the race, for they have off days too. Most important, those who show Good sportsmanship always treat each other with respect.
I realize no matter what sport or otherwise you're going to have those who deny, refuses, opposes, or is skeptical or cynical about one thing or another. Those like that do not have a clue about Good sportsmanship.
As far as this years race and the issue at hand; the rules of racing in Kentucky provide for the disqualification of a horse if it shifts its position in a manner that impedes another horse, costing the other horse a better placing in the race. Although Country House was not materially affected by Maximum Security's swerve on the far turn but at least two other horses were, War of Will and Long Range Toddy. Sports in general have rules for a reason.
