Jockeying for position

Races are hard enough to win without dropping the horse out last and making them overtake the field. So why (oh why) do professional jockeys make it so hard? Both Neroli and Trusting should have won today. Raffaelo too. Great to see my prediction on Irish Lights come true (boy she's good) but half an hour before Speedy's race can I plea that Dunn doesn't take her to the back of the field on the worst race track in the country?
