No way he is second lol. Bama will be picking from the highest branches from the start.
Now...do their top choices turn them down because following Saban may be career suicide and they could have long careers elsewhere? It's certainly possible. If that becomes a common theme during the search, then it's possible they look to an alumni that is not risk averse. That would be Jeremy Pruitt. The guy is gung ho and very confident. He may take the job with neither blinking nor a worry in mind.
But I still have a hard time believing every single top choice would be scared by coaching in the Saban shadow. Surely at least 1 candidate would see inheriting a top 3 team in talent, having 100% community buyin, and being close to top high school talent as great reasons to jump in. The expectations may be crazy, but the inheritance and potential spoils are crazy too.
