Granted, some Dolphin fans will inevitably get carried away with what has been by most appraisals a fine offseason, I'm keeping my expectations in check.
As far as comparing Saban to Spurrier, that is just completely wrong. If you want to say Saban hasn't proven anything yet as a head coach in this league because he is 0-0, thats fine. But the comparison really ends there, Saban was successful in this league as a coordinator, Spurrier was not.
Saban comes in with proven philosophies and experience at the NFL level, Spurrier came in with a gimmicky offense that many including myself doubted would fly in this league.
You can say he's being overhyped if you want, until his teams succeed it won't be disproven, but, what many see, including many that have been very successful in this league, is a guy with a great eye for talent, a guy who is very cool and confident who knows exactly what he is building and has a blueprint. A guy who has the personality to lead and make his players believe in him.
He's also a guy that has succeeded at every job he has had, and had no less than Bill Belichek(winner of 3 out of the last 4 Superbowls) publically state that he learned more from Nick about football than Nick ever learned from him.
