14 time Pro Bowler and 1968 Pro Bowl MVP with 94 career sacks - and he'll still be remembered as a mildly retarded guy on Little House on the Prairie.
He sang to over 220 million people over his lifetime, worked with Billy Graham for over 50 years, and recorded over 500 vocal solos on more than 70 albums. And yet - we had no idea who the fuck he was until we looked him up. Go figure.
