On senior night at Newport Harbor, the Sailors missed three key seniors. Linebackers Ethan Cochran (concussion) and Grant Frazier (foot), and Kory Cablay (ankle), a wide receiver and cornerback, stood on the sideline.
Without them and junior Derek Kula (knee), a cornerback and receiver, the Sailors stood no chance at defeating Edison for the first time since 1979.
The Chargers (8-2, 5-0 in league) went undefeated in league for the second time in three years.
Newport Harbor (5-5, 3-2) finished third in league and earned the league's third and final playoff berth. The Sailors learn Sunday who their opponent will be on the road in the first round.
"Hopefully we get some guys back next week and we make a better showing in the playoffs," said Coach Jeff Brinkley, who led Newport Harbor to its third straight postseason appearance. "Don't know [if Frazier and Cablay will return next week]. All I know is Cochran's done for the year and Kula's done for the year."
Newport Harbor must improve health-wise and offensively in a hurry.
Edison held the Sailors to just three first downs through the first three quarters. If it wasn't for Titus Hasson's 90-yard kickoff return for a touchdown four minutes into the opening quarter, Newport Harbor would've have been shut out of the second time this season.
While the Sailors produced less than 100 yards passing and 100 yards rushing, Edison quarterback Chase Favreau topped both marks by himself.
The senior threw for 267 yards and two touchdowns and ran for 101 yards and two touchdowns. The dual threat led the way for Edison, which has won or shared five of the past six league titles.
"We watched the highlight of the 2009 team. The [13-1] team was pretty special," said Edison Coach Dave White, referring to his team that finished alone in league and reached the section title game.
"We were playing for a championship [against Newport Harbor]."
The Chargers delivered the first blow.
