There's a lot of potential for upheaval in the standings over the next few weeks. The Caps have gone 4-6-0 in the last ten, and are only a point ahead of PIT with the Penguins having two games in hand right now. Meanwhile, the divisional 3rd seeds in the East look tumultuous as well. The Islanders are back in the 3rd spot in the Metro, but the Blue Jackets, Flyers, and Canes are all within 2 points of them. The Leafs are barely holding on to the Atlantic 3rd seed, only two points ahead of the Panthers, who have a game in hand. And the entire West looks wide open, especially the Pacific which has five teams all between 68-70 points (Oilers, Knights, Canucks, Flames, and Coyotes). In the Central, you have the Blues (74), Stars (74), and Avalanche (73) all ready to trade places. (Though Colorado's been hit with some major injuries lately.)
Then, of course, is also the race for best record, which has been noted here has gotten a lot more interesting here thanks to the resurgent Lightning.
It should be a fun next 6-7 weeks.
