Arnsparger, who was born in Kentucky, was a graduate of Miami (OH) University and was also a World War II veteran. Along with being the man behind the two aforementioned legendary defenses, he was also the genius behind the "53" defense, which rigged things so a linebacker could either drop back into coverage or rush the passer as he deemed fit, throwing opposing teams out of whack and forcing them to guess what was going to happen at any given time.
It didn't take long for the news of Arnsparger's death to reach the ears of the Miami Dolphins organization, and they soon released a statement regarding the death of the longtime coach.
