The Edmonton Oilers are working another contract extension. According to TSN's Ryan Rishaug, the Oilers have begun preliminary talks on an extension with forward Patrick Maroon. As Rishaug points out, the term and salary could be tough for the two sides to agree on with Maroon coming off a career year to the left of Connor McDavid. Maroon scored 27 goals and posted 42 points in 81 games last season, he owned 34 career goals through 220 games entering the year.
