Every sport has athletes who can make it in one system and not another. The sport of wrestling (and yes, professional wrestling is a sport) is no different.
Whether you have a wrestler who is too good, too extreme, too big, too entertaining, or who is just a straight-up wrestler. There are some promotions where guys just cannot get over.
There are some names which jump right out but have been left off this list. Superstars such as The Sandman, who made a name for himself in the Land of Extreme but when he jumped to WCW as Hak, he had no character.
In the WWF/E, he couldn't be nearly as extreme as he was in ECW because of the fact that they were transitioning to a more family-oriented television show.
