Assuming the Stewards asked the question maybe it went something like this:
Stewards: 'What happened there Mr O'Brien?' Mr O'Brien: 'I'm a tactical numpty and I don't care two hoots about anyone who backed it' Stewards: ' Perfect'
Being serious absolutely no reason at all for this horse to give the leaders 15 lengths start in a race run at an ordinary pace. Under the circumstances it did incrediby well to finish so close.
