As Robert Cassidy wraps his right hand around the joystick of a power wheelchair, he acts as nonchalant as a kid playing “Need for Speed” on his Nintendo.

“How fast can I go?” he asks Methodist Rehabilitation Center physical therapist Allison Fracchia, as she fits his lanky frame into the sleek chair. “Six miles per hour” is her answer, a reply that prompts a wry observation from Cassidy’s aunt Birteen Burnside. “I can just hear his principal saying: ‘Cassidy, no running in the halls,’ ” Burnside says.

It’s a given that the outgoing 16-year-old will put the customized chair through its paces. The Ruleville Central High School junior is determined to reclaim the life he had before Sept. 1 – the night he broke his neck during the first play of his second high school football game.

After learning he was paralyzed from the chest down — in a newspaper headline, no less — Cassidy admits he fell into a two-week funk. But staying down isn’t his style. “Whatever life throws at you, you’ve just got to roll with it,” he says. “You can’t question God. There is a purpose for everybody.”

Cassidy’s new purpose appears to be a starring role as the inspirational Comeback Kid. Methodist Rehab staffers say Cassidy spent his time at the Jackson hospital motivating patients and employees alike with his hard work and good humor.

”They saw this 16-year-old kid going through this horrible thing, yet he was smiling and dealing with it,” said Jennifer Montgomery, Cassidy’s physical therapist during his more than two-month hospital stay. “When he would finish his therapy, he would befriend the people on the stroke floor. By the time he left, everybody knew him. He seemed to have a really good heart.”

Cassidy’s nurturing nature also calmed family members, who were initially devastated by the sight of the active athlete lying motionless in his bed. “When I first got to the hospital, I panicked for a minute,” said Cassidy’s cousin Cheryl Burnside of Cleveland, a constant by his side since the accident. “But Robert said: ‘Tell her I’m alright, and don’t cry.’ I had to go get myself together then.”

As word got out about Cassidy’s courage, visitors flocked to Methodist Rehab to meet the plucky teen — NFL stars Deuce McAlister and Fred Smoot among them.

Football players and cheerleaders from across Mississippi brought signed footballs, jerseys and collected donations in his name. And Madison Central High Head Football Coach Bobby Hall stopped by every Friday with one of Cassidy’s favorite foods — Kentucky Fried chicken strips. “I’ve been so touched by his attitude,” Hall said.

Hall said Cassidy’s paralyzing collision with another player is something coaches “hope and pray never happens.” But it is a definite risk of the sport. The National Center for Catastrophic Sports Injury Research reports that 256 players sustained disabling cervical cord injuries from 1997 through 2005 – including a dozen in 2004.
