Raphael Lavoie was selected by the Oilers in the second round of the 2019 draft, and has now had a few successful seasons in the AHL. Last season, Lavoie scored 28 goals and 50 points in 66 games, and the Oilers could use that kind of secondary scoring and youth down in the lineup.
As of now, the Edmonton Oilers rank as the oldest team by average age in the NHL. From purely an organizational standpoint, it's a good move to try to inject some youth along the margins, and keep developing players for future seasons. Lavoie will certainly be giving it his all this training camp, and try to make it impossible for the Oilers to send him down.
