I count myself fortunate in that Georgia Tech’s winningest coach was Dodd (70%) who mentored under Bob Neyland (80%). I‘ve followed both programs.
Both heavily advocated speed. We don’t see that at Tech anymore, but Dodd’s teams were FAST. Braun matters but Tech’s historical advantage was always speed.
I saw the same teams. When Bama beat Nebraska in the 1966 Orange Bowl, the biggest player on their OL was Cecil Dowdy, all 6'1", 215 lbs of him. (He was an AA OT, btw.) They
flayed Nebraska. Tech used to be like that. I also remember when Tech went out to LA and beat USCw. Their players were complaining that our DLs were catching their RBs
from behind. They were too. My freshman year our team won 9 games in a 10 games season. Our biggest players were a 220 OT/DT and a 215 TB. The 215 TB, was bigger then most of the DLs we faced. (We were considered for the Grantland Rice Bowl. Luckily, we were passed over. We would have played Tennessee A&I with Claud Humphrey (!) at DE and Eldridge Dickey (!!) at QB.)
All this changed when the NCAA blocking rules changed to allow holding. And I mean, "We won't call it unless you openly grab an extermity or tackle the guy" holding, like the pros. That put a premium on really big, tall guys who had strong upper bodies. And it was done for the tv revenues; the NCAA thought its market share was losing to the pros because they passed more. In some ways this was an advance; I was always taught to block and tackle with my face guard first, a very dangerous technique. Worked, however.
Well, enough old home week. A 1966 Bama or Tech team would get killed nowadays.
