Odds of Rizzi Getting Permanent Job and, If So, What Type of Contract

I can't give odds or contracts and I'm not ready to just hand over the keys to Rizzi. But where does he stand on our HC list? I know people are talking Johnson, Slowick, Vrabel, Glenn, Flores, Cohen and others, but many of these will probably not be coming here. So if these take other HC jobs or refuse the Saints, then at what point do we say Rizzi is the guy? Who has to turn us down for us to go with Rizzi?
