Mangini inherited a 4-12 team too. And they're still alive for the playoffs on the second to last week of the season, more than could be said for last year's Dolphins team (and this year's team makes last year's team look like world beaters).
Stop making excuses for Saban. He made a handful of awful decisions this year-- with the QBs, with the offensive coordinator, with the team's overall malaise coming out of the gates that led to us being in a 1-6 hole before we even started playing at the level of a mediocre team.
If he turns it around, good. If not, then he's out of here (like the majority of college coaches who don't do a thing in the pros) and the Dolphins are right back where we started-- a bad team that needs to be rebuilt (and with JT and ZT three or four years older than they were when Saban took over).
