There are those who firmly believe the Class 5A playoffs don’t really begin until this round.

And they have their reasons.

The first round, for example, didn’t involve the top eight seeds. There have been all of two victories by lower seeds over the two rounds. And last week’s games were won by an average of 22 points.

However, all speculation and preference is moot with the quarterfinals set for Friday.

The traditional heavyweights that have dominated big-school play remain, so there will be no surprise champion … again.

With a combined won-loss mark of 79-11, the great eight of sorts will offer what figures to be a wide range of high-end play labeled below for your viewing pleasure:

(8) Fairview (10-1) vs. (1) Cherry Creek (11-0), Friday, 7 p.m., Stutler Bowl

His Colorado career marks include 11,519 yards passing and 130 TD tosses. … Atkinson will be going against a Bruins defense that is widely considered the state’s best.

(6) Columbine (9-2) vs. (3) Valor Christian (10-1), Friday, 7 p.m., Valor Christian
