It was a lighthearted comment from the Oilers captain, who can't be too stressed about his lack of goal scoring while he's piling up the assists. Still, it's great to see him relaxed and joking about the scoring slump rather than dwell negatively on it.
It's also kind of an interesting comment as MVP debates rage on whether goal scoring is inherently more valuable than assists. Some are arguing in favour of Matthews winning the MVP this year for his torrid scoring pace, but others argue that his lack of assists shows he isn't making the players around him better. McDavid, even in his joking comments, may have cemented himself on one side of the MVP debate, siding with the assists.
