Entering Saturday night’s Hockey East championship game, Terrier freshman John McCarthy — a mainstay on Boston University’s fourth line this season — had only one goal.

So with the Terriers desperately scrounging for a score against a stingy Boston College team, who else did you figure they’d turn to?

“That’s what a championship team is. Goals come from everywhere,” said BU co-captain David Van der Gulik, who had three of BU’s nine goals Friday against New Hampshire. “A lot of times in the big playoff games, who you look to to get the big goals is someone that you’re not expecting.”

McCarthy’s second-period strike tied the game and set the stage for BU’s 2-1 win in overtime. And though Brandon Yip, who scored the game-winner, has nine goals and 28 points this year as Hockey East’s top rookie, his line of freshmen hadn’t scored a goal since the Beanpot.

So on a night when the goals ran dry for BU’s top two lines — which have both been scorching recently — the scoring had to come from elsewhere. It ended up coming from a pair of freshmen playing on BU’s bottom two lines.

“That’s the thing with our team. There’s not one line top to bottom that stands out from the rest,” said BU’s leading scorer, Pete MacArthur. “Maybe the Red Line and the White Line, maybe we score a little bit more, but we get the time on the power play. For Green and Orange to score those goals tonight — that was huge.”

BU coach Jack Parker said getting any offense from the fourth line, which has a more defensive, physical role, is a boost. But he had come to expect goals from the all-freshmen third line, and he met this weekend with Yip, Chris Higgins and Jason Lawrence to make sure they had the right mindset.

“They were trying to be too clever, they were worried about getting goals,” Parker said. “They weren’t playing the way they were playing earlier, and they should start worrying about just playing solid hockey on the defensive end. Play hard, and the puck will go in the net for you.”

It did, for both Yip and McCarthy. And unlike on what Parker might have called “point night” the night before, they needed every bit of offense they got.

“I said to the team after the game, ‘Big goal from the Green Line and the game-winner from the Orange Line,'” Parker said. “‘What’s all this stuff about the Red and White Line? Who do they think they are?'”

B-LINE BLIND

Both Parker and Curry said Saturday that the Terriers tried all day to block out that their title bid was going to be against their archrivals, in the teams’ fifth meeting of the season.

“We didn’t care about who we were playing,” Parker said. “This was about ‘There’s a team in our way, we have to get a trophy this weekend.'”

And while that may have been the case, it was still doubly sweet that it came against the Eagles.

“To be able to do this in the championship twice this year against a team like that,” said Curry, referring to the Beanpot, too, “it’s unbelievable, because over the past few years, you’ve heard a lot about BC.”

DREAM TEAM

Terrier fans were upset Saturday when goalie John Curry was left off the all-tournament team after his gigantic performance in overtime. But the voting took place before the extra session, and BC’s Cory Schneider at that point had bailed out his team much more than Curry.

Three members of the all-league first team — BU’s Dan Spang and BC’s Peter Harrold and Brian Boyle — also made the team, joining UNH forward Jacob Micflikier and tournament MVP Van der Gulik.

KIBBLES ‘ BITS

BC’s Chris Collins, the Hockey East’s Player of the Year, played at 80 percent Saturday night, according to BC coach Jerry York. Collins got hurt running into the goal post in practice Thursday, and didn’t make it through Friday’s 4-1 semifinal win against Maine. He looked better against the Terriers, but still didn’t have the jump that’s made him the nation’s third-leading scorer. … BU’s nine goals Friday were the most the Icedogs have scored in a single game since 1998, when they beat Princeton, 9-1. … Van der Gulik became the first player to ever record two hat tricks in the Hockey East Tournament in an entire career — and he did it in three games. His six goals in the tourney were one shy of the conference record. … BC won the tournament four times between BU victories. … Among the more notable collisions in Saturday’s game was BC defenseman Brett Motherwell’s complete upending of Brian McGuirk. … In the Beanpot title game, BU outshot BC, 36-20. Saturday, in regulation, it was 35-20. … For the second straight year, BU will be in the same region as BC in the NCAA Tournament. But this year, they swapped seeds — the Terriers are the No. 1 while the Eagles took the third seed.
