Last week, they were the two biggest wins of the Penn State ACHA Division I Icers' young season. This week, they are simply learning experiences a young team can learn from.

What a difference a week makes.

Despite sweeping No. 4 Ohio University a week ago at the Greenberg Ice Pavilion, the Icers were not entirely pleased with the performance against their most bitter rival. That sent Penn State head coach Scott Balboni back to the drawing board, which could only be troubling news for his team's next opponents.

No. 3 Penn State (7-2, 7-1 ACHA) will host No. 13 West Virginia (9-5-0) tonight at 9 and Drexel (6-2-0) tomorrow afternoon at 3:30.

To say that the Icers have had success when facing the Mountaineers and Dragons, whom they are a combined 41-0-1 against, would be a bit of an understatement, but that doesn't mean they lazed through preparation this week.

Coming off of the emotional high, Balboni still found time to pinpoint several areas for improvement. The first-year head coach chalked up most of his team's mistakes to youth, but was somewhat disappointed with its execution on the power play.

"We need to make several personnel changes but nothing drastic," he said minutes after Saturday's 3-1 victory.

Against the Bobcats' aggressive penalty kill, the man advantage was no advantage at all for Penn State. The Icers converted just one of 16 opportunities on the power play -- a success rate of 6 percent.

On the season, they have scored on 14 of their 108 chances or 13 percent of the time.

Standing by his word, Balboni wasted no time implementing several new wrinkles.

"We've tweaked [the power play] a little bit right now," he said at practice this week. "We are going to try it out to see if it works and if we are going to actually make changes in the game or not."

The only notable lineup change to the unit is the addition of junior forward Nate Obringer, who will join the existing crew of sophomore forward Luke DeLorenzo, sophomore forward Frank Berry, senior forward Mike McMullen and junior defender Keith Jordan.

Obringer will bring another left-handed shot to Penn State's attack, which will be using only one defenseman to allow for more offensive ability to be on the ice. The personnel tweak is also supposed to revamp the unit's mindset.

"We're switching back more to the unit we had last year. We are looking to move the puck quicker and use that quick puck movement to create more opportunities," McMullen said. "I thought we did well [last weekend], but we're just trying to create more things and use everyone."

Another subtle, but significant change will be the Icers' decision to discontinue using the umbrella scheme -- which opened up in the offensive zone, placed DeLorenzo behind the net and a player in the slot. Instead, they have decided to switch to the overload attack, which will hope to overpower opposing defenses and utilize the unit's offensive savvy.
