I have a much higher opinion of him than you apparently do.

I have been a Cruz donor since before he announced. I’ll continue to send money to him, because I want him on the ticket.
I do not believe, though, that he has the money to fight the GOP-E in the primary and national campaign. In the same way that John McCain’s team undercut Palin and elevated Obama, they will destroy his candidacy if they were to take out Trump, or they will undercut him to elect Hillary. That way their grave train continues.
So, for Cruz to have a shot, Trump needs to win. He has the resources and the contacts to make it happen.
I also think you view the Vice Presidency far differently than I do. A lazy VP is an afterthought, but an involved VP (Cheney) can be a real force. Even independently they have a constitutional role that can make them a daily fixture in the Senate.
Cruz isn’t lazy.
Art I, Sect 3: The Vice President of the United States shall be President of the Senate, but shall have no Vote, unless they be equally divided.
