A boxer would not be able to consistently win outside his weight class. Once, twice against questionable, "higher weight class" opponents, maybe, but not time after time. The Cougs have put together something special made up of a lot of things coming together all at once: overall health and fitness, complimentary football (forgive the buzz phrase) highlighted by an inspired defense keeping them in every game, a maturing of a QB that always had "clutch and poise" built into his DNA, off the charts team culture, unity, player-driven leadership that has created their "good luck." Many other factors at play, I'm sure.
Punching above their above their weight class, nope. Playing inspired, well coached and lead football that keeps them in every game, never losing belief... yeah. 9 and 0 BABY!
