No doubt. The Jets still need to improve their D, and Scheifele's line needs to do a better job of controlling play in their own zone and the neutral zone...
2018/19, 5v5:
CF%:
81-55-26 = 47.5
27-18-29 = 50.9
9-17-13 = 51.8
Scheifele's line is getting a heavy dose of offensive zone starts. Lowry's line is getting a heavy dose of defensive zone starts. Too many shift sequences start with Scheifele's line in the offensive zone, end up in the defensive zone where Lowry's line takes over and moves the play / face-off back into the offensive zone.
Scheifele's line is -5 in on-ice penalty differential. Lowry's line is even, and ELL is -1.
I don't think it's so much a lack of effort, but rather a lack of details and focus on making solid defensive plays and prioritizing a solid zone exit vs. trying to "chip and fly". In my view, it's a very fine balance, and Scheifele's line hasn't got the balance right yet. I still expect them to get it sorted out, though.
Last season (Scheifele and Wheeler together), 5v5:
First half of season: CF 48.2 (54% GF)
Second half: CF 55.7 (68% GF)
