I'm reading the book "Focused on the Top" about our 1990 championship season. Fun reading - the D was the biggest question mark going into the season and turned out to be the biggest strength.
Available on Amazon almost for free, it's a great read. I like to read a chapter or two at a time just to savor it. http://www.amazon.com/Focused-Top-Georgia-Techs-Championship/dp/1563520087/ref=sr_1_4?ie=UTF8&qid=1403472189&sr=8-4&keywords=focused on the top
It is a great read. I got one for my birthday last year from my brother from a different mother.
Also, Jack Wilkinson wrote another book call, "Dodd's Luck". I would recommend that one as well.
