In Super Bowl XVI (January 24, 1982), Bunz made one of the most famous tackles in NFL history. On a critical 3rd-and-goal from the 1-yard line, Cincinnati Bengals quarterback Ken Anderson passed to Charles Alexander in the right flat, but Bunz came up fast, grabbed Alexander around the waist, and hurled him backward before he could break the plane of the goal line. Had Bunz tackled Alexander low, his momentum certainly would have carried him into the end zone.
Bunz is a lifelong Placer County resident who grew up in Roseville with his older siblings Ben and Dennis. He retired from the Detroit Lions at age 30 after a contract dispute, and became a teacher at Sutter Middle School in Sacramento. He and his wife own a farm on the Placer County Wine Trail.
In 1984 Bunz opened Bunz & Company restaurant and sports bar in his hometown of Roseville, California. He sold the restaurant in 1999, and it closed in the summer of 2012. On January 19, 2013, Bunz and some other entrepreneurs opened 2H - 2nd Half at Bunz & Company in the same location as the original Bunz and Company.
