The St. Louis Blues, with their 9-12-7 record and 25 standings points, are only two points back...from dead last in the NHL. Things are not going as planned, and it looks like last year's late-season surge was a mirage; this roster just isn't good enough to compete in a loaded Central Division, and it's past time to face reality. It's time to start rebuilding, and that means trading out aging players for future assets: nobody is untouchable at this point.
Well, that's not entirely true, either: it would be ludicrous to part with any of Dalibor Dvorsky, Jimmy Snuggerud (even though he's injured), or prospects that haven't made the NHL yet, like Justin Carbonneau. Those players are--hopefully--going to be important parts of this team in the future, and trading them for win-now solutions would be ill-advised. You could make the case that Dylan Holloway and Philip Broberg fall in that category as well, among a couple others.
Everybody else, though? If the offer's right, they should be on their way out. Jordan Kyrou and Robert Thomas are in their primes right now, and it doesn't look like GM Doug Armstrong's going to be able to build the supporting cast around them to help them win. Pavel Buchnevich, Brayden Schenn, Justin Faulk, Cam Fowler, Colton Parayko, and Jordan Binnington are all in their 30s and their best years are behind them; the Buchnevich extension, in particular, looks to be nothing short of a disaster, as he's only scored 12 points in 28 games.
Armstrong's put himself in quite a bind, though, as every one of the aforementioned players has some sort of trade protection attached to their contracts--many of them full no-trade clauses, which means they're not going anywhere unless they choose to.
And that's where Armstrong has to start pulling his levers as general manager: finding out where any of Buchnevich, Schenn, Faulk, Fowler, Parayko, or Binnington--even Thomas or Kyrou--would be happy to play. The writing's on the wall for this season, and the future isn't much brighter. If these players want to pursue a Stanley Cup, it probably won't be in St. Louis, and they shouldn't be untouchable if the right deal comes together.
