Interesting map which raises several (endless) arguments. I would think it would be better to be "Regional elite" if you want to be in that region, rather than "elite" or "other top". Moreover, McCombs, for example, is far better than Duke, Darden, Ross, others of that ilk IF you want to end up in Texas. I think really outside of maybe 3-5 schools, most are "regional elite". I'm not going to Stern if I want to work Texas. I realize this brings up endless arguments, perceptions, etc...just my 2 cents.
Also, for regional elite (as a Texan) I would add:
SMU Cox
Rice Jones
Texas A&M Mays
All are somewhere in the Top 50 of the various rankings and all place very well within the state (home of more fortune 500 cos than any other).
Ok that's my TX plugging for the day.
