ST. LOUIS — In his 16 seasons as the St. Louis Blues’ general manager, Doug Armstrong has never had so many assets to work with going into an NHL Draft. He’s got roster players he’s willing to move, a 10th-ranked prospect pool, and 13 total picks Friday and Saturday, including four first-rounders.If you were wondering whether the Blues would be as active as Armstrong continues to indicate they will be, well, they traded Jordan Kyrou to the Washington Capitals Tuesday in a deal that, while not totally surprising, was significant.And guess what?By moving Kyrou a few days ahead of the draft and adding Connor McMichael, Milton Gastrin and the No. 16 pick, there’s opportunity to be even more aggressive.“Yeah, I think it was important for us,” Armstrong said. “It allows the other 31 teams to digest what St. Louis is trying to accomplish and see if they can participate. If we can use some of these assets to improve our team, we will strongly consider it.“Now if you’re one of 31 other teams, you can say, ‘OK, St. Louis has (Nos.) 11, 15, 16, 29. This is what they want to try and accomplish. Do we want a draft pick? What do we have to offer to get it?’ Instead of 12 hours, it allows them 48 hours to really dig in and see if there’s a potential match.”If you think Armstrong couldn’t have been more earnest in the team’s intentions, when asked how far he might try to trade up in the draft, he replied: “If they want to engage St. Louis, that pick — 1, 2, 3, 4 — they know what we have, and I would welcome the call.”Top 5 prospects after the NHL Draft CombineCorey Pronman, Scott Wheeler and moreSo, no, he’s not done after the Kyrou trade.Armstrong did acknowledge Wednesday that the club and Kyrou’s camp mutually agreed after the season that it was best to part ways, through conversations between Armstrong and Kyrou’s agent, Dave Gagner, a former NHL player Armstrong has known since their days together with the Minnesota North Stars in the 1990s.“We talked and they talked about maybe a change might be good for everyone at this point,” Armstrong said. “In the end, both sides felt that potentially exploring different options would be in everyone’s best interest, so we started down that process.”Kyrou, who played eight seasons for the organization that selected him No. 35 in 2016, wouldn’t go as far as to say Wednesday that he was looking to leave, but admitted, “Sometimes just people need a fresh start and a change of scenery.”Armstrong wouldn’t put a number on the teams that were interested in Kyrou, but he noted that the size of the return — a forward in McMichael who scored 26 goals two seasons ago, a prospect in Gastrin who was captain of the Swedish World Juniors team and a first-round pick — should show fans that there were multiple suitors.“Jordan has a very good reputation in the NHL,” Armstrong said. “You score 30 goals a year for three years in a row, that gets people’s attention. In the analytical community, his style of play is also very impressive.
