According to Frank Seravalli, a trade for the big winger is already in place. With the salary cap being what it is, Puljujarvi's $3M cap hit until the end of the season is certainly too much for a contending team like the Oilers, and freeing up this cap space would definitely help them improve other spheres of their lineup.
Jim Rutherford specified that as part of their retool he was aiming for players in their early 20s, players who have not yet reached their full potential. Is Puljujarvi a target for Allvin and Rutherford?
