TUCSON, Ariz. (KGUN) — While much of the sports world is focused on soccer’s World Cup this summer, hundreds of young athletes gathered Saturday morning at Tucson High Magnet School for a different kind of football lesson. Former Tucson High standout and NFL cornerback Levi Wallace hosted his annual Next Gen Football Camp, welcoming children from kindergarten through eighth grade for a morning of drills, instruction and mentorship from current and former football players.
