That's because the McDavid line and the McLeod line are analytics monsters (and Draisaitl, by and large, gets stuck playing with the Nurse-Ceci pairing a lot. Away from them he's 61% XGF%)
Very much so, the Oilers are a legitimate Cup threat. The problem is, there's about six legitimate Cup threats in the West this year and getting out of the conference will be an absolute murderer's row. I could see any of Winnipeg, Dallas, Colorado, Vegas, Edmonton, or Vancouver taking it, and the crazy part is at least two of those teams will be out in the first round.
