I try to follow things very closely and it's not at all obvious to me Buster so you both have me at a distinct disadvantage.
I do know that Casie Coleman was forced by the ORC to race out of the 'D' Barn at Mohawk/Woodbine, this despite never having recorded so much as a positive that would have caused her to have to do so. Further to that I also know that with her 6th straight nomination in a row for Trainer of the Year she took out 'The 2010 O'Brien Award' title for the 4th time. Those who are aware of the very strict criteria which apply to the O'Brien Awards would know that Trainers and Horses instantly become ineligible if they score a Positive during the season.
Casie Coleman having been nominated for 6 years in a row and having won Trainer of the Year on 4 of those 6 occasions speaks volumes and it greatly discredits the inference trotpace is putting across.
