Kane and Foegele are in the top six forward scorers. After that it's McLeod (good). Then the 8th, 9th, and 10th scorers all have ten points or less.
That is relatively low. A team with good depth scoring will have a couple third liners (ranks 7, 8, 9) with 20 or so points at this point in the season (examples: Vancouver, Winnipeg, Detroit, Columbus). Average depth scoring team will have guys in those ranks with 15+ points. There are some contenders like the Avs and Bolts that have comparably weak depth scoring to the Oilers, but they'll fix that at the deadline. The Oilers have to as well.
