I remember looking over one of the programs from that team and was shocked to find that Perdoni was the sole 200+ lb starter. He was a massive 5'11" 235 lbs.
I asked my dad last year why he didn't walk on at Tech (he was a freshman in '58). He was 6'1", 230lbs, fairly fit and athletic, plus he'd been in the Coast Guard for four years, so had 4 years of physical maturity over most of the freshmen. I was like, you could have played for Coach Dodd! His answer was: Well, I never really ever thought about it... I had just married your mom and was concentrating on studying and getting a degree. It's strange to think how small all those guys were back then. By the time I was at Tech, guys like Mike Mooney and Joe Siffri were the kinds of players that were normal in college football.
