(Warning: The video features some harsh language. And old man violence). Joe Kapp was renowned for being a tough mofo when he played for the Vikings. He’s 73 now and obviously hasn’t lost his edge. Look out Joe! Cane! The bad blood between Kapp and fellow former CFL star Angelo Mosca apparently goes back to a cheap shot Mosca laid on Kapp’s one-time teammate Willie Fleming. This happened in 1963. Joe Kapp sure knows how to hold a grudge.
