“I always said I would play ‘til the wheels fell off, and they basically did.”
 
Matt Dunigan remembers the game that ended his career. He was playing with the Canadian Football League’s Hamilton Tiger-Cats in September of 1996, having just made it to the sidelines after a series of big hits and pile-ups that saw the Ti-Cats run out of downs. It was a short reprieve for the quarterback who spent 13 years in the CFL; back on the field, under center, he was ear-holed on two consecutive plays.
 
“When I was helped off the field that day, I knew that my career was over with,” says Dunigan. “Something drastically had changed inside of me. I felt like my armor had been pierced wide open.”

But it’s the little league north of the 49th parallel that could become a vessel for meaningful change in the NFL.
