TechinItEasy, I guess it depends on how you look at it. I have the perception that Clemson has an inferiority complex in relation to our academics. We have overlapping schools (engineering & architecture), and our school has the more formidable reputation. This doesn't only apply to the south, but world-wide.
Now, from the athletics standpoint, I agree with you wholeheartedly. Clemson is our best rivalry and they would be the last off my list. The baseball rivalry is unparalleled. I would bet that it is up there with the best rivalries in college sports. The football rivalry has been great, as well.
With regards to academics, however, Clemson would be one of the first out, for me.
