Buyer's Remorse: Will Mark Pope and Kyle Smith Succeed at New Outposts?

It isn't "just a knife fight (according to social scholars)" and doesn't always pan out for a big-time university after hiring a coach from a fellow power-league member. Poaching within a conference (say John Calipari from Kentucky to Arkansas in the SEC), takes things to an even higher level. Naturally, it's too early to judge whether Mark Pope (Brigham Young to alma mater Kentucky) and Kyle Smith (Washington State to Stanford) this year plus Ed Cooley (Providence to Georgetown) and Micah Shrewsberry (Penn State to Notre Dame) last year will thrive at their new outposts. If not, they'll "fall" in line with the following alphabetical list of prominent coaches who struggled at their new digs after bolting one power conference member for another?
