The United States is a big melting pot, they got every race that excel in each field of strength,endurance,agility and etc. I think we all agree on different race is better suit at different field, for a country like U.S I dont doubt they can bring up a race that is suitable for each sport.
and for Weezy Body size and strength isn't all you need to win, put your big man in certain spots that required reflex and you'll never win. e.g. Ping Pong, Platform diving, skiing.
