This brings up a point I see every year in the AOY voting.
How do you compare athletes that compete in just one event to those who compete in several events? Lewis dominated both the 100 and the long jump, but not as completely as Moses dominated the 400H. I think it's pretty hard to decide which was "better".
How often has the AOY been an athlete that competed in only one event? I think it's 14 times in 43 years.
