Doubt it. This happens every year. The only reason there was a boilover a few years ago was due to a major jockey mistake (arrogance) which took out more than half the field.

Fast forward to 3 mins and watch all the runners who were going to run on be taken out. I count 13 horses impacted and most were in the top chances.

I agree its just ad luck and that riding at the back of the pack causes bad luck to have a higher impact but it was still the action which caused the boilover. I still think the winner will come this year in the top chances in the market.
