It has nothing to do with signals -
I watched the UAB with a local highschool coach who happens to be the top Asst at the winningest public hs in the state - he knew basicallty every play Tech was trying to run each time - he was perplexed by the middle of the 3rd when we basically refused to change our offensive strategy and take advantage of the middle of the field that UAB was daring us to do
That said he was highly impressed with Tech's defense and Baker's growth as a DC over the last 3 years - as he told me - they should of sued Skip for non-support, cause even he could tell Skip was dialing up every play on offense and overriding suggestions from the booth
