Former Bears defensive end Richard Dent says fans enjoy professional football for the big hits and that players understand the risks when they take the field.
"That's what people pay to see," Dent said on the "Mully & Hanley Show" on The Score. "They didn't come to see you play rugby or kickball."
"Just go ahead and give the guys insurance the rest of their lives and quit worrying about it," he said. "Everybody that goes out and plays understands what you have to gain and what you have to lose.
"No one is forcing anybody to play football. [You're] making millions of bucks for that reason."
Head injuries are a hot-button topic as numerous players have suffered concussions this season already, including two Bears. Quarterback Jay Cutler missed the game against the Carolina Panthers because of a concussion in the first half against the New York Giants.
