The Philadelphia Flyers were sailing along just fine this season until they ran into an old nemesis.

Philly was 4-0, with 31 goals for and just three against, Saturday at 8 p.m. Just more than 26 hours and two games later, the Flyers' record was a bit more human.

The Toronto Maple Leafs, with whom the Flyers have played two classic Stanley Cup series the past two years brought sky-high Philadelphia back to the back with a one-two punch of a 6-1 victory Saturday night in Toronto, then 6-3 bouncing of the Flyers Sunday night in the Philadelphia Spectrum.

"This team seems to get up for the Flyers," said Roger Neilson, Toronto's rookie coach.

"Toronto dominated, us," said Flyer captain Bobby Clarke after Sunday night's defeat. "They beat us in every part of the game."

Kurt Walker scored the first goal for Toronto at :45 of the fight-marred contest, Ian Turnbull followed with a goal at 3:05 and Errol Thompson scored on a power play at 6:46.

Bob Kelly got the Flyers' first goal six minutes later before Borje Salming put in what proved to be the game winner at 17:08.

"I thought we were going to win it when we came back, but Toronto took its bumps, didn't lose its cool and was very responsive to its coaching," said Flyer coach Fred Shero. Canadiens 6, Rangers 2
