Who are the 2017 St. Louis Blues? The team has been doing its best roller coaster imitation with a long winning streak followed by a long losing streak -- and then, just to mix things up, another solid winning streak. Management traded away a top defenseman (Kevin Shattenkirk) during that streak of streaks, so it feels like the Blues aren't championship contenders this year. But maybe they’re still playoff contenders? Recent wins against the Minnesota Wild and the Los Angeles Kings have shown there's still fight left in this team. Maybe the Blues can bang into the post-season and then play spoiler. Don't underestimate the power of schadenfreude -- ruining the Blackhawks' season is always a pleasure. Tonight at 7 p.m. the Blues take on the Arizona Coyotes, who are hanging out near the bottom of the standings once again, at Scottrade Center (1401 Clark Avenue; www.stlblues.com). The Coyotes have nothing to play for but pride, so expect a tight-checking game (that spoiler role is also an option near the end of the regular season for some teams). Tickets are $20 to $319.
