FOXBOROUGH – Everett erased any doubts about who was the best football team in Eastern Mass. with a virtuoso performance Saturday at Gillette Stadium in the Division 1 Super Bowl against St. John’s Prep.Crimson Tide quarterback Jonathan DiBiaso hit on 16-of-21 passes for 246 yards and three touchdowns while the state’s player of the year, Matt Costello, caught 11 balls for 145 yards and those three scores as Everett completed a 13-0 season with a 31-7 dismantling of the Eagles.”I think the experience of last year (losing 29-0 to Xaverian at Gillette) really helped us,” Everett coach John DiBiaso said. “St. John’s is a very physical team and we knew they were going to be. But I am extremely proud of this team. They have played well all year.”The Eagles (8-5) goal was to ride workhorse Tyler Coppola and keep the powerful Everett offense off the field. And while Coppola stunned everyone with a 49-yard touchdown run on the Eagles first snap of the game, the Crimson Tide held him to 151 yards and stonewalled the Prep the rest of the night.”(Their record) speaks for itself,” St. John’s coach Jim O’Leary said. “John does a great job with that team. They were on their game (Saturday) and it was too much for us to handle.”Everett (13-0) did not have to puntas it scored on five of its seven possessions. The first possession, however, gave the Eagles a lift when DiBiaso fumbled and Ryan Delisle recovered.Coppola turned that into a 7-0 lead moments later when he broke four tackles and raced to the end zone. Unlike their loss to Xaverian a year ago, the Crimson Tide shook off that mistake and charged right back to tie the game when DiBiaso hit Costello for a 29 yard touchdown, his 41st TD pass of the season, with 5:35 left in the first.”Jonathan did his job very well,” the elder DiBiaso said. “He gets a lot of grief because he’s my son and people think that’s why he’s been so successful. But what he does, he does well. And I’m extremely proud of him.”The Eagles went three and out and Everett put together a rare long touchdown drive, going 74 yards on 13 plays that stretched into the second quarter. Manny Asprilla closed the drive with a three-yard run and Everett was in front for good at 14-7.St. John’s moved into Everett territory late in the half but Tommy Gaudet was stopped on a keeper on a fourth-and-three at the 43. The Crimson Tide turned that stop into a touchdown with 46 seconds left when DiBiaso threw a perfect backshoulder fade to Costello.”We started with a bang,” O’Leary said. “But we’re a team that features a lot of young guys and it was a hard match up for them.”The only points of the third quarter came on Gilly DeSouza’s 22-yard field goal to increase the lead to 24-7. Early in the fourth, DiBiaso and Costello put a cap on a fantastic fall with their third hookup of the night, Costello’s 23rd TD of the season, to ice the game.
