No matter if Leon Draisaitl and the Oilers are far apart on signing a contract, there is no chance this proposal has any merit or logic behind it. Draisaitl is easily a top-5 forward in the NHL, he scored 41 goals and 65 assists for 106 points and a +/- rating of +26.
Joonas Korpisalo on the other hand, is not considered an elite starting goalie. In the 2023-2024 season he went 21-26-4, 3.27 GAA, and a .890 save percentage. If a trade were to ever happen, the Bruins would have too send significantly more to Oilers.
