Welcome to the 2017 Class 5A quarterfinals, not to be confused with the 2016 5A quarterfinals.
However, if you are, we understand.
Seven of the eight teams from a year ago have returned — simply substitute Fairview for Mullen — including two-time defending state champion Valor Christian; Pomona, which has finished runner-up the past two seasons, and Cherry  Creek and Regis Jesuit, which also made the semifinals a year ago.
All have been recognized as recent or long-ago powers. All know how to make playoff noise. All know how to score as well as play defense. And just about all, as in six of the eight, are from the previous Centennial and Jefferson County leagues, so the chances for a big-school champion outside of the historically powerful groups are shrinking by the round.
The one thing the big-school quarterfinals round usually does do, though, is provide arguably the best series of the playoffs. Over the past three decades, the Great 8 has been, well, great, a tough road to a final four.
And the scores figure to be much closer than the nearly 27-point average margin of the preliminaries.
With only three weekends of schoolboy football to go, below is a game-by-game preview  to keep you up to speed:
(8) Grandview (9-2) vs. (1) Valor Christian (11-0), Friday, 7 p.m., Valor Christian
The Wolves are 2-4 against Valor, the last time nearly a year ago to the day, a 66-35 whipping in the — you guessed it — 2016 quarterfinals. … Since 2004, Grandview is 27-9 in the playoffs, an impressive mark under head coach John Schultz, who quietly is closing in on 110 victories since taking over in 2004. … Last week, the Wolves, who have won seven games in succession, beat Lakewood by the mercy rule, wining 42-0. … Grandview rolled to 452 yards of offense, a whopping 372 rushing, a high total for a 5A team.

Joshia Davis rushed for 66 yards and a TD and Blake Stenstrom, sharing time with Luke McCaffrey, was 6-of-11 for 56 yards and a TD. … The Valor defense permitted only nine first downs, had an interception, was credited with four sacks and was headed by Peyton Polson being in on eight tackles.
(5) Fairview (10-1) vs. (4) Pomona (9-2), Friday, 7 p.m., NAAC

A Poudre player and his mother were killed right after last week’s team dinner. … Bigger Pomona news — QB Ryan Marquez returned after four weeks from a fractured wrist.
