Adams was born in Charleston, Arkansas as one of ten children.[2] He was considered normal size until he was 10, but then experienced a growth spurt during which he "shot up like a tree". He attended Subiaco Academy in Subiaco, Arkansas, where he played high school football and basketball.
Adams played college football at the University of Notre Dame from 1942 to 1944. In 1943, he was the backup for Ziggy Czarobski on the 1943 championship team and then became the starting tackle in 1944.
