It's OK, I'm used to sub-par athletics having graduated from Bucknell University. I'll admit that in-state tuition is my number one consideration. You are right that if I went to ECU my family and I could just live off campus and it wouldn't really be a problem. However, since my wife is a stay at home mom, the campus housing at UNC may be a slightly better arrangement (financially).
ECU also sort of scared me off with its primary care agenda. At this point I don't really know if primary care is right for me and in case it turns out not to be, I don't want to have it crammed down my throat (if you know what I mean).
The truth is that I considered several schools in my region (Duke, Wake Forest, Emory, Vandy), all of which are certainly fine institutions, but to me none of them are worth three times the price of UNC. Don't get me wrong, I would go to any one of them (including ECU) if it was the only place that I got in. I guess that I just don't want to pile up tons of debt if I can avoid it.
It also occurred to me that applying EDP might be like putting all of my eggs in one basket (as you suggested). The benefit of EDP is that UNC will know that I am committed to going there and even if I get deferred I will have a good shot at getting in later. If I were to play it safe and apply to the other schools, I would have a tough time answering questions on secondaries like "Why Vandy?" "Why Duke?" Even my answer to "Why UNC?" seems to be a bit lacking, which is my main concern right now.
I have checked out all of these school's websites, but I really didn't find enough info to help me make such a huge decision. Then again, maybe it's not that huge; maybe it doesn't really matter where I go (I don't think the ADCOM's would like to hear that). I know about Duke's research year (but I've never done any research) and their basketball team (I just don't care). Honestly, I think that tuition is much more important than all of the crap that schools try to entice us with (PBL, etc.) but I just don't want the ADCOMs to know that I feel that way.
Can anyone help me out here?
