Over the years you see so many you would consider hard but not necessarily dirty. The worst bit of sportsmanship I have ever seen however was from the talentless Rosco . Rosco had little ability but occassionally could gate. On one particular night at Oxford he made the start in front of the recovering from a serious injury Andy Hackett. Hackett, after taking a year out from injury, was just starting to find his feet again. Rosco leading coming out of the fourth bend was struggling to hold Hackett off. As Hackett tried to over take going down the straight, Rosco turned right into the fence. Hackett never had a chance and never rode again, career over. Ironically, Rosco later signed for Oxford but was never accepted and never seemed to understand why.
