It's like last year all over again. Result of that was a 42-35 loss.
Alabama is perennially good, but they're far from unbeatable.
First, whoever thought that Alabama was going to walk all over Ohio State is an idiot. Second, and this is my opinion and everyone is not going to agree but Ohio State is a better team than Clemson regardless of record. Clemson is good and we will see if they can match up with Alabama, but Ohio State was built to play teams like Alabama so everyone knows what is kind of expected. Regardless of how good Clemson is on both sides of the ball, it wasn't built with the idea that it needs to stop the powerhouses in FBS, instead it's more of let's just be good and win our games.
Go back to the Notre Dame/Alabama title game. Notre Dame was a good team, everyone was going on about how good their offensive and defensive line were based on how they won their games and how Alabama, that year, didn't face anyone with the talent that Notre Dame had. Well the truth turned out to be that Notre Dame didn't face anyone that had the talent Alabama had.
I see this Clemson team the same way. Sure, they went undefeated and ran their schedule but no one from that schedule, September through to December, even comes to close to being on the same level as this years Alabama team.
But, looking at facts, this isn't a cake walk for Alabama. It should be a good game because Clemson is undefeated for a reason but would I be surprised if Alabama won the BCS in the same fashion as they did the Cotton Bowl? Absolutely not because that's what Alabama does in title games (Texas, Notre Dame, LSU). Nick Saban is undefeated in title games and there's a reason for that.
January 11 can't come soon enough.
