World Chase Tag co-founder Christian Devaux argues professional tag will be a multi-million dollar sports business and compete alongside other sports. The childhood game of tag is poised to become the latest "it" factor in professional sports. The league is called World Chase Tag (WCT) and it's touted by its founders, Christian and Damian Devaux, siblings from the UK, as the first and only global league for professional competitive tag. "Tag is the one sport that everyone has played and everyone understands the world over," Christian Devaux said in an interview with Fox News' Douglas Kennedy. "And when you get elite athletes playing tag on a well-designed quad, it's awesome to watch. And that's why I think that within 10 years, WCT is going to be bigger than the UFC."
