The thing you fail to recognize is that teams are constantly in flux. Maryland made the top 20 (2017 #18) one year, Michigan State made it in 2016 (#17). Can GT make the top 20 every 5 years? ABSOLUTELY without question. It's not like making the top 20 requires a class full of 4/5 star players. On average, the #20 ranked class averaged about 7 4 stars per class. You don't think GT can close on 7 4 stars each class? IF the defense AND the offense carry their own weight, it should not be hard for GT to close on that many 4 stars. Unfortunately, with system we have on offense, we can pretty much eliminate any 4 stars coming to GT to play offense. I think we average about 1 4 star on offense every 4 years. Georgia is a top 4 state in producing NFL talent, and top 4 state in producing college players.

Look at the other states ahead of GA in producing NFL and college players. GT does well in Alabama and Florida in recruiting already. Imagine if GT has a system kids actually want to play in, and a system recruits don't get negatively recruited against. 100% true: there are recruiters out there that show a photo of our DLs walking to practice with knee braces on, and tell the DLs and LBs we recruit "Is that something you want to endanger your career with everyday? Having to protect your knees? It's bad enough to play against it one time every year, but imagine having to do that on a daily basis. You're risking money going to GT." True or not, that's the perception GT is fighting against right now with LBs and DLs.
I see the argument about APR when recruiting comes up. Here's the thing: It will be interesting to see how GT does AFTER CPJ is gone. APR was instituted in 2003, and of course we had that vaunted 2007 class. 2008 class was shaping up to be a pretty good class as well until Gailey was fired and CPJ came with his system. From a strictly recruiting perspective, we've had to recruit with the offensive system hurting us since CPJ was hired, so it's hard to get a gauge how GT would do now that APR is in full bloom. If anything, APR affects are still TBD.
