If a hockey team is fortunate enough to light the lamp five times in a game, it should come away with the win. With double-digit goals, it's almost a certainty. That kind of scoring can't, and won't, happen in every game.

The No. 1 Penn State ACHA Division I Icers know they must continue to focus more on stopping their opponents' scoring, instead of adding to their own totals.

In their last six games the Icers have averaged just less than eight goals. During that stretch, they also bombarded opposing goalkeepers for a three-game streak of 10 or more goals.

However, during that same six-game scoring run, the Icers have allowed more than three goals per game. In four games against two top-10 teams, they gave up an average of 3.75 goals.

This weekend's series against No. 8 Michigan-Dearborn showed a bit of improvement as the Icers tightened up from a 10-5 win on Friday to hold the Wolves to three goals in Saturday's win.

"Five goals" is what the team was thinking about Friday night, senior forward Luc Walker said.

Icers head coach Joe Battista had been working with the team on defense all week, hoping to shut down an opponent without relying on a high-powered scoring attack.

"Offensively, I'm very, very happy to see us continue to move the puck, and a lot of different guys scored -- but man, defensively, we've got to get better," Battista said after Friday's game. "We absolutely have to get better on defense."

Saturday night's lineup even featured some defensive-minded changes from the previous game. Forwards Mike Diethorn and Marc Switaj and freshman defenseman Scott Dakan all suited up.

Battista had recruited Diethorn because of his defensive skills, and Switaj has been known to change a game with his big hits. Also, Battista said Dakan contributed a great game, as the Icers try to cope without senior defenseman Matt Wallace, who has been out all month due to injuries.

With defense in mind, the Icers allowed only one even-strength goal during Saturday's 5-3 win. Not a perfect defensive game, but an improvement.

"We did a little bit better, giving up only three goals instead of five," sophomore defenseman Keith Jordan said Saturday. "We want to limit their shots even more. We really want to tighten up that even more than we are if we want to play solid defense in nationals and against tougher teams."
