Henrythenavigator wasn't as good as Ravens Pass that year. Decent Group 1 winner but no better. I'd guess he wouldnt be in the top ten of O'Brien's milers. The ratings are the best method of measuring the performances of horses who never met. The reason why Excelebration is rated higher is that he has beaten/been beat by horses better horses than Henrythenavigator. Its not perfect, it measures the performances they put on the track not actual ability.
Same with Giants Causeway. Because he is remembered fondly, especially in the Breeders Cup, but horses like Greek Dance, Best of the Bests, Observatory not to mind Kings Best murdering him in the mile.
Is it that surprising to believe that Excelebration couldnt beat Greek Dance, Best of the Bests, Observatory...
