According to LSN, my buddy and I had the lowest LSATS (2 points below the 25-75% range) of any non-URM's accepted to my school (Top 20). Anyway, we both finished in the top 20% of our class (him a little higher then me). I got a great job and he transferred to a top 5 school and got an even better job.
I think your work ethic in undergrad is more of an indicator then your lsat score. Those that managed to do well with respect to GPAs while managing difficult majors, work, sports, etc are the ones that are doing well in law school with some exceptions obviously.
Do yourself a favor and dont sell yourself short because of your lsat though. You may have a lower lsat but dont feel like a loser. Your gpa is probably drastically higher then that of your classmates and there is a reason the school accepted you. I personally was intimidated about my competition at first.
