Pluses: The top line of Mikko Rantanen (24 points), Nathan MacKinnon (21 points), Gabriel Landeskog (18 points) have been unstoppable all season. They have accounted for 27 of Colorado's 52 goals (51.9 percent). That puts a big emphasis on them each night and they have come through time and time again.
Goalies Semyon Varlamov and Philipp Grubauer have been very good this season. Not including the last two games, when they allowed 13 goals in losses to the Flames (6-5 on Thursday) and Vancouver Canucks (7-6 in overtime Friday), but that wasn't so much on them as it was the team. The defense has improved from last season, although we can see based on the past two games there still is work to do.
Minuses:They have got to get scoring outside the top line. It's unfair and unreasonable to expect them to contribute as much and as often as they have for 82 games. Their next highest scorer after their big three is defenseman Tyson Barrie with 11 points, all assists. The only other forward with double-digit points is Alex Kerfoot with 10 (two goals, eight assists).
Colorado has lost three straight games (0-2-1), and had a lead in each of them. They were ahead 1-0 after the first period against the Minnesota Wild on Oct. 27 but lost 3-2. They had a 4-1 lead entering the third period against Calgary, and the next night they had three one-goal leads against Vancouver, including two in the third period. Those defensive lapses need to be fixed, especially against a Predators team which can make them pay.
