The New York Rangers boast a 3-2 lead going into tonight’s quarterfinal Game 6 against the Philadelphia Flyers (7:30 p.m., ET, NBC Sports Network). However, history would suggest they may have to play a Game 7.

On paper, the Rangers seem poised to move to the next round to play the Pittsburgh Penguins. But here are factors favoring the need for a Game 7:

Home is an advantage

Since 2011, home teams facing elimination (at any point in the series) are 31-16 (66%). The Wells Fargo Center should be rocking tonight with the Flyers vowing to play more aggressively

Odd Rangers history

New York is 13-2 in series when leading a series 3-2 going into Game 6, but the Rangers have lost 11 consecutive games in which they have had a series lead. The Rangers also have not won a series in fewer than seven games since the first round of the 2008 Stanley Cup Playoffs

Flyers have been resilient

The Flyers dug out from a slow start this season, and they have answered the challenges they have faced this season. Coach Craig Berube converted the Flyers to a defensive style that was a good fit for postseason play.

We haven’t seen the best from Philadelphia

Claude Giroux (one goal, two assists, 10 shots on goal) hasn’t had a strong series and the Flyers aren’t getting enough shots on goal. They haven’t played their best hockey yet in this series and they believe tonight is the night. They are hoping more aggressive play will result in more turnovers and more shots on goal.

Mason is stepping up

Henrik Lundqvist has been sharp in the Rangers’ net, posting a 1.81 goals-against average and .920 save percentage. But the Flyers have looked sharper since Steve Mason returned to the net. He has stopped 55 of the last 59 shots he faced.
