BOSTON – It’s the goal that most local kids dream about scoring when they lace up a pair of skates for the first time: one that helps your team play for a championship.For kids growing up on the North Shore, playing in the Beanpot is the culmination of a lifelong dream. And for Saugus native Jason Lawrence, that dream has been a reality for the past three seasons.But Monday night at TD BankNorth Garden, Lawrence experienced a thrill that not even he probably could have imagined.The senior forward rifled a shot over the shoulder of Harvard goaltender Matt Hoyle on a power play with 1:46 left in regulation to give newly anointed No. 1 Boston University a 4-3 win over the Crimson and send the Terriers to their 24th Beanpot title game in the last 26 years.The Terriers will play Northeaster, a 6-1 winner over Boston College, in the final next Monday night at The Garden.”Growing up in Saugus like I did, you watch the Beanpot and dream of being there,” Lawrence said. “You idolize these guys growing up and dream about scoring a goal like that.”The goal was simply a thing of beauty and it came after Harvard’s Pier-Olivier Michaud had tied the game with a power play goal of his own at 14:33 of the third.With 2:10 to go, the Crimson’s Doug Rogers was called for hooking, giving the No. 1 ranked power play unit in the nation a chance to steal away the win.Defenseman Colby Cohen fed a pass to Lynnfield native Cam Higgins, who took a Harvard defenseman with him before dropping the puck back to Lawrence in the left circle. The senior skated to the face-off dot and unleashed a rocket that Hoyle had no chance at stopping.”I just put my head down and drove it,” Lawrence said about the winning goal. “Luckily it went in.”Lawrence’s goal nearly wasn’t the winner, however, as the Crimson pulled Hoyle for an extra attacker with a minute to go and nearly forced overtime.Off an icing by BU with eight seconds to go, Harvard looked for the equalizer and looked to have gotten it when Alex Biega blasted a shot past Kieran Millan as time expired to tie the game at 4-4.Officials went upstairs to the video goal judge and it was quickly determined that Biega’s goal had come a half-second after the clock struck zero and BU escaped.”It was a close call, obviously, and they probably made the right call,” Biega said. “The play was heat of the moment and I really don’t have a say.One thing the Crimson did have a say in was making BU play one of its worst periods of the season to begin the game.Harvard (5-12-4) put the pressure on the Terriers from the outset and needed a little under half a period to take a 1-0 lead as Michael Biega scored off assists from Eric Kroshus and Rogers at 8:32. Though they wouldn’t score again in the first, Harvard would go to the locker room knowing they had a 2-man advantage for 1:49 at the start of the second period.”We knew coming in after the first that we hadn’t played our best hockey, knowing that we had to play BU hockey,” Lawrence said. “We knew it was 5-on-3, tried to kill it, they got a goal but then we killed off the rest of it.”The Terriers plight didn’t get better as Harvard did take advantage of its 5-on-3 chance when Alex Killorn scored an unassisted goal at 1:04. But BU killed off the rest of the power play and went about getting back in the game.St. John’s Prep and Terrier co-captain John McCarthy helped get BU back in the game as he earned an assist on Nick Bonino’s goal at 12:13 that cut the Crimson lead in half.Moment later, the Terriers were on the power play and back even in the game.McCarthy’s co-captain, three-time All-America Matt Gilroy escaped a check along the left wing boards and fed a pass to Bonino for a shot that beat Hoyle to tie the game at 13:56.And there it stayed until fourth liner Zach Cohen gave BU its first lead of the night with 8:35 to go when he scored off a face-off. But Michaud tied it three minutes later, giving Lawrence a chance to play hero.”They worked hard and matched our intensity, buy
