Pens and Devils are duking it out for the Division lead. With identical records, it's the head-to-head play that has the Devils in front, pushing the Pens to 4th.
If the playoffs were to start to day, Pittsburgh would be facing the Sens in the first round. They are 2-2 in the season series with Ottawa, with each team winning once at home and once on the road, and with each team blowing out the other once. It's about as even as they come, but I think the first time they faced a fully-healthy Senators lineup was the Jan. 28 game, which the Sens won 4-1. Since then, they have added Mt. Sutton and Cullen, and Karlsson has emerged into a top offensive defenseman (and, no, I am not exaggerating -- it remains to be seen if he can continue his impressive string of games into the post-season). And if that's not enough, there are plenty of players left from the opening round sweep two years ago.
If Pittsburgh can heat up in their last four games and pass the Devils, then their first round opponent will likely be Montreal. Although the Pens won the seasons series 3-1, this is a different Habs team, now that Halak has been given the #1.
Pittsburgh is 5-5 in their last 10 (well, technically they are 5-4-1) and they clearly need to be a better than .500 team heading to the post season. Heating up with 4 games to go is what they need, but would facing Halak in the first round be a bonus or curse?
