Greatest Living Racehorse?

[miraja2]

If you include Cigar (in his prime) into the fields of any of Ghostzapper's last six races....how many of them would Cigar would have won?

It is obviously impossible to know, but my guess is zero. Ghostzapper probably still would have won them all.

That's certainly not the only factor one should use in determining "greatness," but I do think its pretty important.
