I still think you are missing the point. Each of the three Triple Crown races poses a different kind of challenge. The schedule is the least of it. They are run at different distance over different kinds of tracks. But the challenge is only meaningful if the winner is racing against the 3 year-olds who are best capable of meeting that particular challenge. A souped up sprinter can compete in the Derby and sometimes win. But you wouldn't want to see a Belmont where the lead horses were staggering down the stretch, just trying to hit the finish line. It wouldn't be a good race, and there wouldn't be much glory in winning. So who would care about the Triple Crown then?
It's always exciting when a horse is on a streak. Apart from Secretariat, the most exciting horse I ever saw was Cigar. And he wasn't even in the Triple Crown. But streaks happen when they happen. If the conditions of the race rule out your toughest competitors, then the streak doesn't mean a thing.
No, I'm not missing the point. I just offered a different opinion. But thanks for playing.
