So what happened to Casino Drive

[Bobby Fischer]

at some point it should have clicked that speed horses weren't going to finish on that track.

Well Armed was a complete toss before the mile, and he was a better fit in his respective race than Casino. When the Catalano horse also went to the pace in that race $$$$$

I think the thing to do in the classic was tossing casino and fairbanks completely out of the top 4, and as soon as Casino went to the lead, you really didn't look at him again and started screaming "navigator"
