Alabama has been so scary good all season that it’s easy to have nightmares about them while preparing for Saturday’s SEC Championship Game in Atlanta. They’ve been that good.

It’s one thing to win all 12 games, but it’s another thing to win them all by 20 points or more, something that hasn’t been done in college football since Yale way back in 1888. Yale won its 13th and final game that year by only 10-0, so Alabama has a chance Saturday to do something that no team has ever done.

Now, how scary is that to think that the Crimson Tide could go out and crush Georgia by three touchdowns? It could happen, and it could be even worse. Hence the nightmares. Alabama won the National Championship Game 26-23 in overtime last year, but Alabama is a much bigger favorite (13 points and rising from its 10.5-point opening) this time around.

Here are five of my biggest fears on how this could all go so very wrong on Saturday:

1. Tua Tagovailoa sits back and picks them apart all day

On Sunday I watched Philip Rivers of the Los Angeles Chargers complete an NFL-record 25 passes in a row and my first thought was that Alabama quarterback Tua Tagovailoa could do the same thing against Georgia. There are several reasons this could be a perfect storm and something crazy like that could happen.

First, Tagovailoa is extremely accurate, probably the best QB Alabama has ever had. Secondly, his speedy wide receivers are always open. Add to that an offensive line that’s very good and a Georgia pass rush that’s last in the league in sacks, and Tua could pick the Dawgs apart. Georgia has had only 20 sacks, and its 1.67 average per game ranks No. 101 in the nation. Those are all very bad combinations.

2. Alabama front takes away run game, makes Dawgs one-dimensional

Georgia ranks No. 13 in the country in total offense (480.8 yards per game) because they’ve been able to balance the run with the pass. Everyone thought there would be a dropoff in the Dawgs’ running game this year after Sony Michel and Nick Chubb graduated, but it hasn’t happened. D’Andre Swift and Elijah Holyfield have been that good.

But Alabama’s front seven is so good that they can take the run away from just about anybody, and it could very well happen again on Saturday. A Georgia team forced to throw all the time is a scary thought. Alabama, ranked No. 6 in the country in total defense, can really bring it up front.

Alabama is 5th in the country with 40 sacks.

3. Tide’s goal-line defense keeps forcing field goals

As good as Georgia’s offense has been, it’s been downright awful around the goal line. There have been several instances where they haven’t been able to pound it in from a yard or two away and were forced to settle for field goal. Heck, against Florida they tried six consecutive times to score from the 1-yard line or close, and missed every time.

Alabama’s defense gets even better in tight spaces, so this could be a huge problem area for Georgia. It’s going to be critical in this game to get touchdowns instead of field goals, because they’re going to need all those points to keep up with Alabama’s lethal offense. This is the game-changer right here.

4. Alabama’s offensive line creates huge holes in running game

Alabama’s run game gets overshadowed because of the greatness of Tagavailoa, but they are still averaging 205.9 yards per game on the ground. Damien Harris, Najee Harris and Josh Jacobs are all great backs, and they look really scary behind that huge offensive line that looks like a road grader when they’re running downhill.

Georgia has dealt with a lot of injuries up front all year, and they’ve never been completely healthy or overly impressive this season. This could be a matchup where Alabama completely dominates, and if they’re running the ball well, the play-action passes could be there for the taking, too. Georgia likes to pride itself on being a physical team, but we’ve seen what happens when a team gets its running game going. Remember the loss at LSU? The Tigers ran for 275 yards. Could the same thing happen again on Saturday?

5. Nick Saban makes better decisions than Kirby Smart

Nick Saban is the greatest coach in college football history. Sure, he’s had great players, but the Alabama coach has almost always made great game-time decisions, too. Inserting Tagavailoa into the National Championship Game last year might have been his best call ever.

Kirby Smart is his protege, and he learned his craft at Saban’s side. But still, he’s just a third-year head coach still learning his way, and he does have the occasional brain cramp, and that can’t happen Saturday. The ill-time fake field goal at LSU still comes to mind.

On the sidelines Saturday, there’s an edge to Alabama and Saban. Here’s to hoping it’s not a huge game-deciding edge.
