Our youth are missing out on one of the most enjoyable sports ever created:

 Calvinball.

Calvinball is perhaps the only sport with only 2 rules:

Wear a mask and never play it the same way twice.

Calvinball, unlike most other games, develops it's players creativity rather than their brawn as they make up whatever rule to help them "win."

Furthermore, Calvinball is the world's only truly inclusive game as the only thing needed to play is imagination. Stadiums aren't required, neither  expensive uniforms or equipment. 

And there lies ESPN's greatest opportunity: a sport with almost zero expenses. It also has a greatly reduced chance for injuries, saving them a number of legal and PR issues.
