Back home in Newington, Conn., Campanello had faithfully tuned into Gators games for more than three seasons, hoping to catch a glimpse of Murphy, who starred for Campanello's team at Wethersfield High School.
Like Murphy, Campanello was rewarded for his patience and perseverance in ways he never imagined during Florida's 31-17 win against Tennessee.
Murphy, a redshirt junior, had not thrown a college pass prior to Saturday. But he came off the bench to ignite the Gators' offense with his timely scrambling, clutch passing and surprising calm in trying circumstances.
"I thought he played within himself," Campanello told the Sentinel on Sunday. "You go into a situation like that, I thought he was really composed. He was going through his progressions. He just handled the whole situation really well.
"He made the right decisions. When he scrambled, it was at the right time. He picked up a bunch of first downs. He threw it well. I just thought he ran the whole offense effectively."
Campanello was not surprised, though he was understandably anxious when Murphy entered the game.
"I was nervous for him because you never know when you get into a settling like that, his first true exposure," Campanello said. "But was I surprised? No. I always thought if he had a chance he would do OK."
Murphy always had the mental and physical makeup to succeed, even at college football's highest level, his former coach said.
Murphy would arrive at Wethersfield High around 6 a.m. each day to lift weights before class. He was also a good student, and in his spare time, he worked with special needs children.
"He was a good example to the other kids," Campanello said. "He was real respected. He just carried himself real well and had a presence about himself."
On the field, Campanello said Murphy "was kind of a man among boys within our program."
Murphy once scored six touchdowns during a game — four running and two on returns — against Tolland High. As a senior, Murphy earned all-state honors as a return specialist after Campanello went against conventional wisdom and let his starting quarterback field punts and kickoffs.
The first kickoff Murphy returned that season resulted in an 85-yard touchdown. He had five touchdown returns "until they decided not to kick to him anymore," Campanello said. "He was pretty dynamic back there."
Yet Murphy was lightly recruited — and initially not as a quarterback.
Campanello said Connecticut offered Murphy a scholarship to play safety, while Syracuse and Temple recruited him to play wide receiver. Gators offensive coordinator Steve Addazio saw Murphy's dual-threat potential at quarterback, but Murphy originally picked Temple before switching his commitment to Florida.
Murphy arrived in 2010, but he spent the next three seasons on the scout team. He moved into the backup quarterback role when Jacoby Brissett transferred to NC State in January.
"Yeah, it was always in the back of mind that I might never play," Murphy said. "I just kept working hard and just keep fighting and kept faith in myself and kept praying for my opportunity. It wasn't the way I wanted it, but an opportunity is an opportunity."
Murphy's unwavering faith impressed his high school coach.
"I have to give him a lot of credit," Campanello said. "He is very strong-minded. He has a lot of confidence in his abilities. For him to stick with it that long to try to achieve one of his goals, I think is one of his strong suits.
"That's why I'm so happy for him that he did stick with it."
Gators fans are, too.
With each play Murphy made Saturday, a sellout crowd at the Swamp grew louder. By the time Florida took a 31-10 lead on Murphy's 7-yard touchdown run, Gator Nation had renewed optimism in an offense that entered the day last in the SEC with just 40 points in two games under Driskel.
More than 1,000 miles away, Campanello could not contain himself, either.
In between plays, he texted with his wife, who was out of town; his daughter; one of his assistant coaches; and other people in the community. Mostly, though, Campanello cheered on his former player.
"I was clapping and jumping up and down and just thrilled every time he made a good play," he said. "I was like a little kid."
After the game, Campanello traded text messages with Murphy. The quarterback does not return to Connecticut too often, but he keeps in close touch with Campanello and appreciates the people back home.
"He said, 'Thanks, coach.' `Tell all the players I said hi' and 'Go Eagles,'" Campanello said.
