Biggest gap between the best horse in a crop and the rest

[Indian Charlie]

As DrugS was enthralling me yet again about how Rose didnt give afleet alex one of the dumbest rides in derby history, it occurred to me that in the last 20-30 years, it's possible that Afleet Alex might be the biggest standout in a single crop.

Now, I'm not saying that Afleet Alex is the best horse of the last 3 decades, but can anyone find an example of a horse that is that much better than the next best horse in their crop, compared to alex vs the rest of his junky crop?
