John Parrella has resigned as the Valley Christian High football coach and taken a job as the defensive line coach at Chabot College.
Jim Heal has been hired as the Vikings new head coach after coaching special teams under Parrella.
A former Oakland Raiders defensive lineman, Parrella turned the Valley Christian program into something special after starting the team from scratch six years ago.
He guided the Vikings to their fourth straight North Coast Section Division IV playoff berth in 2012, before falling to Sir Francis Drake-San Anselmo 18-13 in the first round.
"I feel like if I was going to leave that this would be a great time to leave," Parrella said. "The program is sound. They've got a great team, a very good football team coming back for this year. All the coaches are staying, so I felt that program was finally solidified, and I wouldn't have to move. I still have kids in high school. I have a son (Cal) that's going to be a senior. It was good to keep him here for his senior season."
Parrella played in three Super Bowls during a 12-year NFL career after starring at Nebraska.
He has fond memories of coaching at the small school in the Dublin hills.
His upstart 2009 team thrilled the community by advancing to the NCS semifinals before losing to Justin-Siena-Napa. The 2010 team advanced to the first round, and the 2011 squad made it to the second.
But he couldn't pass on what he considered a "great opportunity" to coach at Chabot.
"I've been thinking about coaching at the next level, and coach Danny Calcagno gave me a great chance to get my foot in the door," Parrella said.
He considers Calcagno to be an outstanding coach that "truly cares about the kids on the team. They're two-time conference champions. A chance to be a part of that winning tradition that he's built over there, I'm really just glad to be a part of it," Parrella said.
