Times columnist Helene Elliott rates the pluses and minuses in the NHL from the last week:
+ Tampa Bay center Steven Stamkos became the first player to score 30 goals this season, reaching that mark Friday. But he's one of the few bright spots for the Lightning in a season gone sour. Tampa Bay's defense and goaltending have declined sharply and the team is winless in seven games in January. The Lightning will be sellers at the Feb. 27 trade deadline.
+ The Detroit Red Wings set a club record Monday by winning their 15th straight home game. With the 5-0 victory over Buffalo, the Red Wings have outscored opponents, 68-21, in that span. Away from Joe Louis Arena they're only 11-13-0, but they're too good for that to continue.
+ The Nashville Predators have won five straight games and eight of their last nine and are 14-4 since Dec. 8, putting them in a playoff position. But hanging over their success is the question of whether they will keep or trade standout defenseman Ryan Suter, who can be an unrestricted free agent July 1. They haven't gotten Suter to re-sign and they don't want to lose him with no return. He left their 3-1 victory over the New York Islanders on Monday because of an upper-body injury
