If you're hellbent on clerking, go to Yale. 50% of Yale grads get a federal clerkship. If you want to work in academia, go to Yale.

If your ultimate goal is to work for Big Law for a time and then work in the public sector, choose the T10. Clerking is a great experience, but it is not a prerequisite for Big Law (although clerks receive a snazzy $80,000 signing bonus when they join a Big Law firm).

If you are confident in your ability to perform in law school, go to the T10. Among T14s, class rank will limit your options more that your school's name.

If you perform well (top 10% of your class), take the appropriate classes your 2L year, and earn a position on Law Review, you will be competitive for a clerkship regardless of which T14 you attend.

Note: Law school is hard and fiercely competitive. By design (forced curves), 90% of the class will not be competitive for a clerkship due to class rank (except at Yale and Harvard where the top 50% and top 20-30% will be competitive, respectively). If you're confident that you can perform better on law school exams than 90% of the students in your T10 class, then pick that option without a second thought! But consider that nearly every law student wants to be the top of his or her class and your classes at either school will not be filled with slackers. The battle to the top is hard fought.

Finally, debt sucks. And it accrues interest. And it certainly limits your choices. Many believe that Big Law will allow you to quickly pay off your debt, but this is not the case. It will still take the better part of a decade (if not longer) to pay off your debt unless you go full miser. And most Big Law attorneys leave after 2-3 years because the work-life balance is truly horrible. On the bright side, though, there are tons and tons of Big Law job openings each and every year because the turnover is so high.

Food for thought. I voted for T10 plus money.
