Hey Neub, I am in a similiar position to you regarding BC. I am on a few waitlists at some T-14's. I am trying to not get my hopes up, but I am not really feeling BC at the moment. I'll get into that after I address your concerns.
In my opinion, yes any T-14 would be an easy pick over BC. BC seems to be a great school, especially well regarded in the Boston area. However, from all the anecdoctal evidence I have read from various sources, each source says that you MUST finish in the top 1/3 of the class to get one of these BIGLAW jobs. I feel that this is a fairly accurate statistic since I've seen it pop up so much. I realize that there are a few exceptions, but who really wants to plan on being that one exception to the general trend? At any T-14, it seems that firms go deeper into the class than from any 20-30 ranked school. Sure it may be difficult to get a firm job in Boston (a finicky legal market) if you are middle of the class at any T-14, but you probably will find a market rate (125K) associate position. You can always lateral to a Boston firm if that is where you truly want to be.
I think it was wise choice to pick BC over the others if your inclination is to stay in the Boston area. Hands down it seems BC gets their grads more firm placement than GW and even BU in the Boston area.
Okay so here is my situation, if you have any thoughts I'd be glad to read them. So I am choosing between BC and Minnesota. Both gave me nothing in terms of money, outside of the standard 18,5K Stafford loans. Thus, it would be much cheaper for me to go to Minnesota than go to BC. When I started the application process, I told myself money wouldn't sway me away from a school, but 150K in debt is a whole lot of debt (my debt load if I attend BC). If I got to Minnesota, I am instate, it would be about 100K. So that is something I am thinking about. My personal preference would be to go to BC, but I am worried that I will assume massive debt and not be able to find a market salary job if I don't do well enough. I also don't feel that BC would give me an advantage in job prospects over Minnesota. Would BC give me an advantage in job prospects? If I do well enough at either I probably won't have problems. I also have no preference for where I want to study law (maybe NYC, but probably on the East coast).
I am hoping to snag a spot of a waitlist, but I can't really count on that. Well, this post is long enough. Let me know what you decide!
