Big Time Recruits who "flipped" after a visit?

In the recruiting discussion, there has been significant debate on the difference between "expressed interest" and where someone actually is going to end up going. For instance, it is prob. rather likely that Christian Jones will go to FSU (I trust Tom VH's judgement.) If I were a HS kid who hadn't been around the country, for sure, I'd be interested in flying, eating, visiting, going to a game, on someone else's dime. For some of you road warriors, and those whose family's resources allowed you to travel/fly extensively, it's no big deal. But for a kid from the middle of nowhere (think Pahokee) or from an area no where near a big city/big airport, flying around the country is pretty cool. Going to a game in the Big House, visiting USC or UCLA, maybe making it to Washington, it sounds pretty cool. What I'm interested in is the history of recruits who have flipped after an official. Have any flipped to us? Flipped away from us? Does the "snake oil" have anything to do with this? Regardless, it's impossible to guess the mind of a recruit. Who knows how much PT, family influence, NFL prep, team rankings, feeling a part of a team, getting along with coaches, especially position coaches, and a ton of other intangibles, really matter. All that can really happen is for the team to play well, the coaches to reach out to the guys they truly want, and let the chips fall where they may.
