In 2015 they played Wisconsin, 2016 Southern Cal, 2017 FSU, 2018 they'll play Louisville. Granted these are neutral site games, but they are on the schedule. Tech should keep some non-Power 5 games on the slate, but our home schedule should look more like last year with one big Power 5 name outside of UGA. This year 25% of our schedule is non Power 5 and thats just not going to generate any kind of buzz around the program.
The issue with comparing Alabama's schedule to Tech's is that Auburn is an in-conference game for them and UGA is an out of conference game for us. So, yes, Alabama played Wisconsin, USC, FSU, etc. the last few years, but every one of those years we played UGA. Here is a comparison of the
next best two OOC games for each program over the last 5 years:
2013 - Alabama (Colorado St., Ga. St.); Tech (BYU, Alabama A&M)
2014 - Alabama (Fla Atlantic, Southern Miss); Tech (Tulane, Georgia Southern)
2015 - Alabama (MTSU, UL-Monroe); Tech (Tulane, Alcorn St.)
2016 - Alabama (Western KY, Kent St.); Tech (Vanderbilt, Georgia Southern)
2017 - Alabama (Fresno St., Colorado St.); Tech (Tennessee, UCF (canceled))
All things considered, I would say that Tech has played a harder OOC schedule than Alabama the last 5 years. Aside from the neutral site games Alabama played that you referenced, they didn't play a single power 5 conference game OOC. Tech at least played BYU, Vandy, and Tennessee.
