I'm an American, but I think Americans have this flawed sense of "athleticism". For whatever reason, hockey, baseball, and soccer players are rarely included. It seems as if you have to play in the NFL or NBA to be an "A level athlete". Wayne Gretzky was drafted or signed by the Toronto Blue Jays I believe. Joe Mauer had a full ride to be Nebraska's QB and was all-state in basketball. People just choose the big muscular guys and label them A level. Plenty of those guys have very little stamina, which is a part of athleticism. Cristiano Ronaldo is ripped to shreds and almost beat a Olympic sprinter in a 60m race.
A true A level athlete to me is someone like Lesnar. D1 National Champion wrestler, UFC HW Champ, made the Vikings without having played football for like 10 years. For his size, he has one of the craziest combine numbers you will ever see: 40 yard - 4.7, Vertical - 35 in, Bench - 30 reps....at 285 lbs. That's outrageous.
