Many have said the Seattle Seahawks defence just might be the best of all-time.
After all, their Super Bowl opponents boasted the greatest offense in the league's history - and the Seahawks nearly shut them out.
They held an offense that routinely embarrassed opponents to just eight points. They scored defensive touchdown after defensive touchdown. They forced fumbles, interceptions and safeties.
They stopped the unstoppable.
But this just might be the best, most unbelievable statistic of them all.
The official NFL Twitter account tweeted: "The Legion of Boom DOMINATED the postseason. Without committing a defensive penalty. How'd they do it?"
How on earth did they do it?
That's a pretty insane statistic. I know Richard Sherman, Kam Chancellor, and Earl Thomas III are all ridiculously talented players.
But to not concede a single penalty, especially considering the physical brand of defense the Seahawks made their own, that's a hugely impressive feat.
So, who is backing a repeat next year?
