I was going to respond to your other BA post that he has the inside track IMHO.
1. He will come cheap because he has NO shot of being a HC elsewhere.
2. He comes from within, so as to ease the concerns of the players. He also has a read on what transpired in recent years.
3. Being the ST coach, you know Marv is looking to create a real legacy and what better way than to give an opportunity to someone to follow in his footsteps. (this is the kind of decision making that will scare me about Marv).
I don't see how it will be anyone else at this point...
