I mean, employment prospects at SU are pretty atrocious...
at least at a top 30 school, biglaw firms come to OCI. Not sure if biglaw (esp. not non-Seattle biglaw) would come out to SU OCI. Not saying that biglaw is the end all be all, but in terms of opportunities it's a pretty important one to have.
I agree that, overall, employment numbers at TTT schools are worse than overall employment numbers at T30-T40 schools. (Though there's isn't that much daylight between some of the T40s and some of TTTs.) And if we were talking about a median student at a T30 versus a median student at a Seattle U, I would of course agree that the latter is worse off. But that's not what we're talking about.
We're talking about someone who is one of the top five students in his or her class. In general, TLS underestimates the value of being one of the top few students in your class at a lower-ranked school. If you're ranked that high, you don't need OCI to get be competitive for firm jobs in your region. No, you're not guaranteed a firm job, but neither is a student who is median at WUTSL, Minnesota, or Arizona.
I agree with the TLS conventional wisdom that one shouldn't go to a lower-ranked school if the goal is to land a decent-paying firm job. But if you actually end up as one of the top students in your class (as the OP has), you're going to be in good shape. I'd rather be top 2.5% at at Seattle U than median at just about any school outside the T14. And if my goal was to work in Seattle, I'd rather be top 2.5% at Seattle U than median at many of the T14s.
