My take:
Start Kosko next time, obviously.
McDavid was much better defensively than a lot of people gave him credit for. He was directly responsible for the Saad goal, turning it over behind the net. After that he played with more spark, and I noticed him back checking like crazy almost every shift. I'm not sure about his line at even strength, however. He played well himself, sparking a breakaway and a near goal for Nuge + Kassian. But there wasn't much chemistry going on. I'd move back to the Nuge - Drai - Yams line, and potentially move Neal up to the top line until Kassian regains his form.
The 2nd line was decent, not great. They had a few good cycle shifts, and a shotpass from Drai to Yams that was an inch away from going in. Like I said before, I'd switch Nuge and Ennis.
The 3rd and 4th lines were both underrated at 5v5 in my opinion. The Sheahan - Archibald - Athanasiou one didn't have much, but they did hit a post after an AA rush. He looked extremely fast btw, the D have to learn how to feed him on the rush. The Neal - Khaira - Chiasson line actually wasn't bad. Chiasson hit the post on a one-timer, and they had a few nice cycle shifts and some good physical play. Apart from scoring a goal, they did their jobs.
Nurse and Bear were much better than Klefbom and Larsson. Tippet seemed to recognize that and played them much more at ES. 19 ES mins for Bear, 21 for Nurse, and 15 for Klefbom. 2016-17 Klef - Larsson have to come back. Weirdly I actually thought Russell had a really good game. He joined the rush multiple times and actually contributed offensively.
The next game is a must-win. If we lose we're a game away from elimination, if we win it's all tied up.
