Dan Bylsma can't coach speed.

His Penguins players, however, must quickly do a better job of defending against it.

Improving upon "emotion and spirit" would help, Bylsma said Tuesday night after a 4-1 loss to the New York Islanders that kept the Penguins without a point after two games at Consol Energy Center.

With only 24 home games in the truncated NHL season, that trend must change fast.

The Penguins (3-3-0, 6 points) have fizzled after a fast start with road wins over the Flyers and Rangers.

This loss looked a lot like the one at Winnipeg on Friday and against Toronto in the home opener a week ago.

"I would say our speed gave them problems," Islanders center Frans Nielsen said after recording two assists in his club's victory.

Goalie Marc-Andre Fleury was replaced for the third period by Tomas Vokoun. Fleury made just 13 saves.

Penguins defenseman Brooks Orpik said that neither he nor his teammates did anything well against the Islanders. In fact, only a late goal by right winger Pascal Dupuis prevented the Islanders from their first shutout in Pittsburgh since 1985 or anywhere against the Penguins dating to 1986.

Sidney Crosby was born in 1987. He is not entirely convinced the Penguins are playing slower than in past seasons.

"I don't know if I've analyzed it that hard," Crosby said. "We try to play a quick game, transition fast. With (virtually) no (training) camp, maybe we aren't. But it hasn't been something I've noticed."
