You could say the same thing for a few teams in the country (probably 10 of the 12 teams in the CFP).When we are playing our best football, it does look like we can beat anyone. But mostly, we've only seen that in bursts.
OP wrote our defense is built for this...and I agree. I would add that our lines are built for this.
Lines travel. We have good lines and good vet QB.
If we play focused good football for a long sustained time, we'll win. If we play like that, but only incrementally, we'll lose.
I think this is a fairly even matchup. Might favorable them by a bit because they are at home.
