Somebody who plays baseball or some such type of shitty American sport. They're the only a-level athletes apparently, despite the fact that half of them are fat and they don't compete on an international stage.
Haha. Nicely done.
I think a lot of the trouble comes from specialized sports dominating the Olys and Major American sports. Ie. guys get to the top if they are really, really really good at doing ONE thing. But, anytime someone can chuck a shotput or run a marathon at a really, really high level it is due to genetic predisposition to that one movement plus specialized training in that movement/duration.
Mikey Phelps is an A-level athlete, but we only know this because he dominated a highly competitive sport. He has huge hands and feet, short legs, a dolphin's torso and insane shoulder rotation. He's been built to succeed at swimming.
When a sport is well-rounded and involves strength, power, flexibility, mental toughness, anaerobic/lactic thresholds, speed, aerobic capacity, etc etc etc - then there simply isn't an athlete who could be highly successful at a sport like that WHILE being world class at a specialized sport.
An A level football player, lifter, runner, swimmer, jumper, thrower, gymnast, pitcher is a different type of A-level than is an A-level; rugby player, MMA'r, crossfitter, decathlete.
But, the beauty of well-rounded sports is that there is a place for anyone who adapts the training. You can be weakish in some areas, and don't have to be the very best at any area - and still be competitive if you put your game together to the best of your genetic abilities.
