My Grandpa talked about Beattie all the time. He always said he played like Jim Thorpe, they called him "Big Chief"
BF ended up Coaching College ball. I never saw him play though to answer your question. Just heard he's no Feathers a lot.
I should have added these guys to my initial list to begin with, all were great tailbacks coming out of high school that unselfishly made the move to fullback for TN. While not the flashiest, they all were steady and did a lot of things really really well to help the VOLS win games.
James Stewart wasn’t as good as Cobb,Webb, Lewis and Henry, but he was as reliable as they come. Led the team in rushing his freshman year. Then lost a ton of carries to Charlie Garner for 2 years. Then led the team in rushing again his Senior year. He absolutely annihilated the UGA defense his Senior year with a 1st baseman playing QB.
