Additional Details:
DET- Rasmussen wasn't Yzerman's guy it was Holland's. Dillon Dube is a lot closer to an Yzerman player than Rasmussen, Dube has a lot of the traits Brayden Point and Anthony Cirelli have. Dube is also a much better skater. For reference Dube 0.30pts/g, Rasmussen 0.29pts/g, in the AHL Dube 1.0pts/g Rasmussen 0.63pts/g.
EDM- nobody will give a 1st for JP. Maybe they can get a 2nd though. But in this case, Holland goes for his "guy" that he spent a 9th overall selection on. Rasmussen could be the #3C the EDM roster lacks.
CGY- hurts to trade Dube, but the Flames really liked JP in his draft. They say they wanted to trade up for Tkachuk... that's all lip service, it was for JP. The Flames also have Gaudreau, Tkachuk, Mangiapane, Pelletier, Lucic locked in on the left side for another 2 years. LW is an area of organizational strength.
