How Bad is this Derby Betting Strategy?

[miraja2]

I agree with others that ALL is not a smart play in the Derby. There are always at least a couple horses that you can definitely toss because they have demonstrated that they have absolutely no desire to go 9 furlongs, let alone 10. Start by identifying and getting rid of those horses.
Each year's Derby is unique so make sure you are basing your betting strategy around your handicapping analysis, and not the other way around. Good luck.
