At the end of an emotional week, Philbin wasn't ready to let up.
The Dolphins channeled their coach's intensity with impressive results Sunday.
Ryan Tannehill threw for 288 yards and three scores, and Miami forced four turnovers to rout the San Diego Chargers 37-0.
Philbin missed two days of practice leading up to the game to be with his father, who died Friday in Massachusetts.
Following a moment of silence for the elder Philbin before kickoff, the Dolphins won one for their third-year coach.
"I really have to give our assistant coaches and our players a ton of credit," Philbin said. "I kind of just showed up for the game."
Afterward, Philbin's shirt was soaked, thanks to a sports-drink dousing by his players.
"We promised him we would play our best game of the year, and we did that for him," guard Mike Pouncey said.
Philbin's iffy job security has been bolstered by recent results. The Dolphins (5-3) earned their third consecutive victory as they began a stretch of four games in a row against playoff contenders.
"We're scratching the surface," Philbin said. "We certainly haven't put it all together yet."
The Chargers (5-4) remained winless in South Florida since January 1982, a stretch that includes eight consecutive losses to the Dolphins. A midseason swoon worsened with their third loss in a row.
"We'll get this back on track, I promise you," coach Mike McCoy said. "No doubt in my mind."
San Diego was shut out for the first time since 1999, while the Dolphins earned their first shutout since 2006. Every Miami victory this season has been by double digits, and this was the most lopsided yet.
Tannehill had a career-high passer rating of 125.6 when he called it a day after three quarters. He went 24 for 34 with no turnovers and threw touchdown passes to Charles Clay, Rishard Matthews and Jarvis Landry. He also ran for 47 yards on four carries.
Meanwhile, Miami's front four dominated the Chargers' line, harrying Philip Rivers into a lost fumble and three interceptions, two to Brent Grimes. Rivers passed for only 138 yards and had a quarterback rating of 31.0, his lowest since 2007.
Rivers went to the bench for good late in the third quarter, and the Dolphins ended his Chargers-record streak of at least one touchdown pass in 28 consecutive games.
"They flat-out beat us," Rivers said. "For 60 minutes they wore us out."
The final score could have been even more lopsided, but the Dolphins stalled four times inside the Chargers 10-yard line, and those possessions netted a total of only nine points.
"We're just tapping our potential," Tannehill said. "But words are cheap. You've got to go out and do it every week."
