I know it's a small sample size, but one slightly concerning trend is Draisaitl's play under Woodcroft's system. I wonder if he's the type of player that dislikes structure or that takes longer to adjust because many of his plays seem automatic or habitual, such as the one-timer on the PP or the backhanded passes. Now that he has to take the time to adjust his play style, think critically, and develop new habits, it may mean a relatively longer learning curve.
I know its been mentioned that personal player points don't matter as long as the team's winning and I largely agree; however, 1) McDavid has started to show signs of accelerating his point production, which means that the same effect SHOULD happen to Draisaitl and 2) the team needs Draisaitl to contribute offensively in order to have sustained success. It's been great to win without one of your major stars contributing, but at some point, they'll need him to step up his production again, especially to make and have some success in the playoffs.
Again, I can't say if he's just taking an extra long time to adjust to Woody's system or if this is just a continuation of the prolonged doldrums he's been experiencing since December. Last year, when he went through this same problem, it only lasted 1 month to 6 weeks at the most, but now it's going on 3 months, which, at this point, is a bit of a concern. Hopefully these concerns are premature but something to keep an eye on. Woodcroft seems like a great communicator, so perhaps he'll make some headway with this issue.
