Both Perry and Brown's salary bonuses will be applied to the team's cap next season. Together, their bonuses will make up a significant $3.5M in space, which will take up almost the entire cap increase of $4M. With three goals, two assists, and two fights in his first ten games, Perry is proving to be well worth his salary bonus and may even be worth a contract extension next year. Brown on the other hand, his salary bonus will be a pain in the side of Oilers management next season.
These salary bonuses for ten games played are fairly odd to see twice in one season for a team, especially when they didn't seem to take advantage of it. Perry has already well earned a spot on this team before his ten game bonus, but Connor Brown was clearly struggling greatly before he played his tenth game. If the Oilers cut bait with Brown then, they wouldn't be on the hook for his salary next year - in hindsight, that probably would've been the best decision.
