If the US News & World Report model actually captures good things about a university, then what's wrong with attempting to match that model?
That a university tries to match what it considers a good model shouldn't be surprising. The validity of the model may be questioned. The methods to match the institution to that model may be questioned. But I don't see how attempting to get better under some model they consider good (by whatever criteria they pick) is bad.
I don't know enough about it to know if the USNews model is any good - maybe, maybe not. But I know that institutions I'm generally familiar with land about where I might expect in the rankings. Ivy leagues on top, small underfunded state colleges much lower.
Now, the claim that Clemson administrators purposefully rank other universities lower, that's a different matter. That is the most troubling claim to me in the whole bit. That action is highly unethical and I would be sorry to find out that it is true of Clemson, or anywhere for that matter.
