Canada's "Crazy Canucks" men's DH racers from the late 70s to mid 80s begs to differ. Of course they did it by having Podborski, Read, Irwin, Murray, capable of a podium finish in every race so if one faltered another would flourish and by so doing they operated like a team sport....
Ahh, imagine a peloton. What they could have accomplished. Or, short track style.
