there's an abundance of evidence that suggests these athletes are crossfit athletes because they did not achieve the same level of success in conventional athletics. None of them are professionals or achieved the same earning potential in any sport other than CrossFit. You can suggest that they may be capable of it, but the fact is that they are not currently. If Rich Froning was good enough to be a professional baseball player, he would likely be a professional baseball player. If Dan Bailey was capable of being an Olympic sprinter, he'd likely be an Olympic Sprinter. If Sam Briggs were capable of being an Olympic Rower or an elite Iron-Woman, she'd likely be one.
The best athletes, at least in this country, are funneled to conventional sports long before they are pushed to the sport of competitive exercising.The best conventional athletes may very well be capable of being professional exercises, but the inverse is more likely than not, untrue.
