BigLaw (in and out of Utah, insofar as anything in Utah is "big") firms have caught on to BYU/LDS grads (and to a degree, grads from other places) to earn a boat load of cash to pay off loans, get training and experience, and bail for the first available position. I couldn't tell you how the slump in hiring new attorneys with the bottom falling out on the market affects things, but that is potentially a confounding variable to the anecdotal evidence that BigLaw doesn't recruit BYU very hard anymore. Very few grads are getting placements in BigLaw (even among the top students), and all that I know of had to work hard to create the opportunity.

FWIW, my only experience with BigLaw was getting one interview with a BigLaw firm (not Utah based). The interview consisted of the attorney telling me (and from what I understand, others) about the long hours and weekends you'd be required to work, the lack of time with family, high divorce rates, etc. horrors about BigLaw to see if anyone was truly committed to the lifestyle and avoid hiring someone who was intending to bail within a few years. Fine by me if that's how the firm wants to further their interests. Not for me though.
