WWE Hall of Famer Ric Flair commented on Mulligan‚Äôs passing via Facebook:
My friend since 1976. A man among men. We drove 3000 miles a week for 8 years. TOUGH does not begin to define Jack Mulligan. He was the baddest of them all. I was honored to be joined by his eldest son Barry in the four horseman. If anyone ever deserved to be in the WWE HOF it was Jack. My condolences to the Mulligan/Windham/Rotunda families. His memory lives on as his grandsons Bray and Bo are tearing up the WWE as only the Windhams can! You will be missed Blackjack.
