The St. Louis Blues are “engaged in serious discussions” with the Ottawa Senators on a trade that could involve forwards Mike Hoffman or Derick Brassard, according to a new report from Blues beat writer Lou Korac. Citing a source, Korac reports if the two teams complete a trade, it will be for one of Hoffman or Brassard but not both. A potential package going back to Ottawa could include forwards Vladimir Sobotka, Patrik Berglund and Robby Fabbri according to Korac. The Blues have already been active on the trade market, acquiring forward Nikita Soshnikov from the Toronto Maple Leafs on Thursday. Hoffman’s name has been in trade rumours most of the season. Back in December, Sportsnet’s Elliotte Friedman reported the Blues were interested in trading for the sniper, who has two more years left on his contract.
