I don’t have numbers, but it definately helped Tech. It was a bigger help for uga, though.
I agree with you 100% re: UGA. US News rankings have a suspect methodology but their rankings are well publicized and widely read. If you compare the ratings of UGA v. Tech in 1999 versus now, they have closed the gap wrt to US News rankings considerably. I would have to do deeper research on it but they have jumped considerably and they made leaps and bounds in the 1990's around the time of HOPE. They were a ööööing joke into the 80's but they have climbed considerably. So has their endowment, it's less than ours but they are gaining.
Clearly, they are close to topping out but they are not a joke of a school (overall) and haven't been for a long time. Sure, they have joke majors and, yes, can hide athletes who cannot read on an early H.S. level but that doesn't mean they haven't become an academic player.
Their lobbying for comprehensive engineering was so much more about getting research funding than anything to do with football. They will be sucking hind tit in the sciences compared to us for decades but they cannot be easily written off anymore. They have always had a pretty strong Biological Sciences programs and their Mathematics is really pretty decent, especially number theory. Their are also very strong in Physical Chemistry and Quantitative Chemistry.
See, what most people might not understand, is that once you open the floodgates to comprehensive engineering, you are going to have a much bigger pool of students taking science classes so the natural science schools are going to benefit to a very large extent.
To their credit, they have been looking at the big picture. I don't know what Tech has been doing but our state is growing and can support several large research universities. It isn't going to be as simple as trying to get a medical school (extremely expensive) or a law school (expensive and sort of mission creep).
