Revolving door for prep football coaches

 Football is often looked upon as the sport that sets the tone for the rest of the season.
 That in itself provides pressure.
 The demands have turned high school football into a year around sport. If you're chasing a CCS title, you're talking about a 17 week season in pads.
 It has also become the sport that showcases the largest turnaround in coaches over the last decade.
 A look at the 17 county high school programs shows 12 head coaches have come aboard in the last five years. That doesn't include the eight coaches that lasted three years or less.
 Marina will be looking for its third coach in three years after Michael Dulisse stepped down Monday after one season.
 Before Sean Gomes returned at North County four years ago, the program saw seven coaches come through in seven years, including two in the same season.
 This from a program with the second most league titles in the county over the last 35 years.
 It's a grind.
 No coach gets more scrutinized or questioned than a high school football coach. No sport puts more demands on a player in terms of off-season conditioning.
 Seeing Al Avila approaching 30 years as a head coach at Seaside in mind blowing. Jeff Carnazzo will begin his 20th season at Palma next fall.
 While an infusion of youth could keep some coaches in the fold, the trend of seeing coaches check out after a few seasons is likely to continue.
