Boston College's move to the ACC will backfire.
Marshall's move to Conference USA will backfire.
South Florida's move to the Big East will backfire.
Texas at El Paso's move to Conference USA will backfire.
Texas Christian's move to Mountain West will backfire.
Nrthrn95, good you noted these, and I agree with you on each of these except for one: Marshall may end up being a good C-USA fit. The geography is not extreme, and athletically, they appear compatible, primarily in football.
The three others, do come across as "stretches" and cases could be given that each could/should have stayed in the conferences they were in.
I have reservations as to Marshall ending up in an expanded BE anytime soon, and the competition in C-USA may be just a tad more of a higher profile (at least potentially) than the MAC, if not, a greater degree of diversity. The MAC is so heavily concentrated in Ohio and Michigan, that any school outside those parameters may tend to keep an eye open for other possibilites if/when they ever exist (Northern Illinois?--in & out & back in).
I recognize C-USA has expanded westward and now has a major Texas/Oklahoma dimension. However, there are still a few eastwardly and central south schools maintaining themselves in the conference.
I tend to favor UTEP as having stayed in the WAC, and maybe, N. Texas joined them. LA Tech is more geographically suitable for C-USA. Of course we heard UTEP's reasons for being more associated with their Texas brethern. But TCU bolted to the MWC, hoping for bigger things, yet leaving their Texas compatriates. Go figure? A mixture of inconsistent rationales we all heard.
