Bo Jackson: If I Knew Risks, I'd Have Skipped Football

Turns out, Bo didn't know football, and if he had, he never would have played. Bo Jackson, who starred at the pro level in both football and baseball decades ago, tells USA Today that he would not have played football had he known about the concussion risks. "Never," says the 54-year-old. "I wish I had known about all of those head injuries, but no one knew that. And the people that did know that, they wouldn’t tell anybody." He adds that he would never let his kids play football today. (In his heyday, Bo famously starred in a series of "Bo Knows" commercials for Nike, as seen here.) One other interview nugget: Jackson says he planned to retire from football after the 1991 season to concentrate on baseball. His NFL career ended prematurely in a playoff game that year when a hit fractured and dislocated his hip. (More Bo Jackson stories.)
