What the hell, I'll keep playing Devil's advocate
What, in your words, is Duke all about as compared to Memphis?
You're still implying that what "indicates" a kid being a good fit for Duke is based upon whether or not they actually end up choosing Duke, which I disagree with. The way I understand it, you're not far off from saying that a kid isn't a good fit for us unless he chooses us. Maybe it's just a Memphis thing but I hope that's not how you feel about every other school besides Duke. We don't get every kid that is a good fit for us and every kid that is a good fit for us doesn't always end up in Durham. Heck, one of the reasons I find Hansbrough so annoying is that I could so easily picture him in a Duke uniform. That's a kid I believe would've fit right in at Duke.
I realize Duke and Memphis aren't identical schools but if the two schools were that night-and-day then why would Duke ever recruit kids that listed Memphis as another possibility? McDonald is the 2nd kid in 3 years that we're competing with Memphis for. We happened to get EW but him choosing Memphis wouldn't have changed the fact that he is/was/would've been a good fit for Duke.
Either you really don't think too highly of Calipari and Memphis or you're making Duke out to be more unique than it really is. Playing basketball at Duke is a wonderful opportunity. But it ain't the only school where that's the case.
