He will likely hit 60 points, but I don't see him getting to 20 goals.
He's currently at 16g 40a 56pts.
At this point, a playoff spot pretty much looks locked up; and I expect Johnny & Mony to be rested for at least one or two games near the end of the season. The Flames have 7 games left, so maybe they play 5-6 games. Unless he gets a hat-trick against COL or LA, he's got to get 4 goals in 5-6 games, which hasn't been his pace.
I saw a table/chart a couple of weeks ago that shows Johnny has contributed (goal or assist) in ~70% of the team's goals. That's far higher than McDavid or anyone else on the list, so I'd prefer our top-players to be well-rested for a long playoff run
