What is crazy is that Hager was actually decent in WWE, but dude was so fucking boring, one can't even remember he held the WHC at one point.
WWE's recruiting process also reminds me of when they managed to get Stacey Ervin Jr., Simone Biles ex-boyfriend and actually a very good gymnast, who had the looks and charisma. Dude got a concussion and said "yep, this is not for me". I believe it's the case for many, many people, hyper-athletic or not. Even linemen in AmFoot have a very short shelf life due to head trauma, imagine removing the protective gear.
