"From the day I got here, I said we would be champions," the coach said. "And that's what we did."
In claiming the program's first state title, the Prep (12-3) exploded for four second-half touchdowns. The Hawks held the previously undefeated Vikings, who came in averaging 43.8 points, scoreless over the final 27 minutes.
"There's no better way to go out," Hawks senior quarterback Chris Martin said. "This is the ultimate goal coming into the season. It's about believing in yourself and in each other."
Martin, who returned from a left-knee injury in a state-quarterfinal win over District 11's Parkland, completed 13 of 21 passes for 192 yards and three touchdowns.
"The coaches wanted me to be careful after coming back," the captain said, "but if it was going to be the difference between us winning and losing, I couldn't do that."
With the Prep trailing by 14-10 at intermission, Martin, who plans to have offseason surgery and play football at Johns Hopkins, connected with wideout John Reid and tight end Joe DuMond for scores of 59 and 14 yards, respectively.
"He was an unbelievable leader on this team," said Prep senior linebacker Ryan McNulty of Martin, who passed for more than 2,200 yards and 27 TDs this season.
The Vikings (15-1) managed 191 yards rushing on 45 attempts, but only found the end zone on quarterback J.J. Cosentino's 1-yard, first-quarter keeper. "We stacked the box, focused on stopping the run," McNulty said.
Scoring runs by D'Andre Swift (35 yards) and Vince Moffett (16) put the finishing touches on the convincing victory.
"We knew all year that we had a chance to do this," Moffett said. "We went game by game, followed the process. No game was more important than the other."
