The VP pick will be the one who the nominee thinks can help him best politically. It generally goes that way.

I think Trump is clever in leaking/refuting all these VP rumors, though.

It gives the media something to talk about, it engages the public, it spurs interest in the convention. And most importantly of all:

If freezes potential third-party challengers. Why would Kasich ruin himself for Romney when he's got a chance for the #2 slot with Trump? Same with Cotton from Arkansas. Same with General Mathis.

Those three names have appeared on third-party wish-lists, and they've also been the subject of Trump rumors. Coincidence?

First of all, there is a 0% chance that Romney or any of these people are going to run third party. That’s all a myth. And Trump isn’t going to pick Kasich, Cotton, or any of those people.

You really do not understand Trump. He hates politics. He doesn't like playing games. He hires people with the best qualifications to accomplish tasks, not do-nothing vote magnets.
