For the immediate future, moving Evander Kane to the Long Term Injured Reserve will actually be beneficial for the Oilers. Kane's $5.25M salary will come off the books, giving the Oilers salary cap space to sign RFAs
Philip Broberg and
Dylan Holloway. Currently, the Oilers are around $350K over the salary cap. The best case scenario for the Oilers may make use of a strategy the Golden Knights have used in recent years - Kane could be on LTIR all season, and play in the playoffs, with the Oilers exceeding the salary cap.
