Huge crowds. Big wins. In-check egos.

The Chicago Blackhawks are doing everything right in a breakthrough season.

On Friday night, Chicago matched the team record with its eighth straight NHL victory, beating Philadelphia 5-1 in front of a franchise-record crowd of 22,712 — the Blackhawks' 16th straight sellout of the season.

"It's tough to find a weakness in our team right now," Patrick Sharp said after scoring his team-leading 19th goal of the season. "The best thing about these eight games is that our team's stayed pretty mellow the whole time. We're enjoying the ride, but we're not getting too far ahead of ourselves."

Andrew Ladd, Brian Campbell, Kris Versteeg and Dave Bolland added goals, and Nikolai Khabibulin made 17 saves. The Blackhawks, 11-1-4 at home and 19-6-7 overall, also had eight-game winning streaks in December 1971 and January 1981.

"This team has lost only one game at home this year for a reason," Flyers coach John Stevens said about the Blackhawks. "I thought we were cheating all over the ice. We ended up taking too many penalties."

In Chicago, the Blackhawks took a 2-0 lead in the first 3 minutes.

Ladd beat Martin Biron on a rebound at 1:13, and Sharp scored at 2:35, lifting a hard wrist shot over Biron from the crease.

After outshooting Philadelphia 14-1 in the scoreless second period, Chicago broke the game open early in the third. Campbell and Versteeg scored on 5-on-3 power plays, and Bolland also scored in the first 6 minutes.

"We did a lot of smart things tonight," Chicago coach Joel Quenneville said. "Took shots, went to the net. ... This was one of our better games all year, in all aspects."
