New Orleans Saints cornerback Lonnie Johnson Jr. has reminders tattooed on his body that signify the violence and despair he escaped in Gary. He’s not quitting on his home town, though. On Saturday, Johnson returned to a freshly renovated stadium at the West Side Leadership Academy to host his third “Protect the Youth” football camp, sponsored by his foundation. About 350 kids, ages 8 to 18, raced around tires and tossed perfect spirals under a sunny blue sky on West Side’s new bright green artificial turf football field. Johnson and 2014 Merrillville graduate Ryan Neal, who plays for the Tampa Bay Buccaneers, and 2014 Thea Bowman Academy graduate Antonio Pipkin, a free agent quarterback in the Canadian Football League, led the drills with West Side coach Alger Boswell. “It looks a lot different,” Johnson said gazing at the football field that received a $936,000 upgrade last year.
