They outplayed the Canucks in 4 of the past 6 periods. It ultimately comes down to goaltending and defending:
1. Don't give their best goal scorers time and wide open shots, have some structure.
2. Get at least average goal tending.
Accomplish this in the upcoming games and you give yourself a legitimate chance of beating them.
If not, you are done. McDrai scoring 6 points per game points won't change anything about this.
I'm not necessarily a pessimist, but considering that, against the Canucks, this team has now won 0 out of 7 games in regulation, it doesn't give much hope that they will win 3 of 4 games.
"Let's just do it again" will not work. Changes have to be made right now, not mid-game tomorrow nor when the Oilers are down 3-1.
Also: I'm not sure about separating McDrai again. McDavid was invisible without Draisaitl in game 1 while they were together for the sole win in game 2. Combined they also seem to be the only line that is able to apply constant pressure.
