Divisional best by decade since 1900

[The Indomitable DrugS]

I was a fan of Curlin but he's very hard to include as an older horse. His big celebrated win as an older horse was a very weak Dubai World Cup.

He for sure could be included as a 3-year-old. That was a total case of splitting hairs - but those sound defeats in the Derby and Haskell and losing to Rags to Riches in the Belmont don't help him. The older horses were awful when he was around.
