He'll be 25 early in the new season with about 2 seasons under his belt. I am not arguing that he can't improve at all, because I think a change in his approach could pay large dividends, but otherwise he is who he is. The skill development and understanding of the pro game, probably not going to evolve much. Not impossible as guys follow nonlinear development paths all the time, but barring a conscience effort to play a different way, I think he is what he is.
I think he needs to learn to pick his spots better. Like when the team needs a spark, or if the Rangers are cowering out there. The difference between his dad and him is that his dad knew
when to stir shit up and when not too. That's why a lot of the things his old man did came as a surprise in the middle of a game versus not- even though it shouldn't have.
That's the difference between using his skills in a more impactful way in the confines of the game versus not. When it's just personal beef out there, then it's a side show, ie veering in that staged fight realm. Which isn't a bad thing if he was in the WWE. But to be able to use all of the mechanics that the game allots, and what he is willing to do out there... that needs to be far more contextual in terms of when and why he does it. There's nothing wrong with a little psychological warfare out there.
The easy way to ingratiate yourself to bigger contracts is to step up and help change the momentum of the game. If I was Lems, I would go balls out the games where a guy above him in the line-up coasts it a bit. Brendan's had a season and change on this roster, he knows that's coming.
The other major component to add is more shots. Lemieux isn't a great playmaker unless it's in that down low cycle, or in front of the net. Speaking of cycles, he's got to get better at that as well. I think simplifying his game to go hard to the net, and get shots, and finishing more checks are what I would look for from him. Even if he's not killing penalties, if he's doing the above then he's going to get another deal that's far bigger than what he just got. The offense is a byproduct of effort with him. This isn't a dainty skilled guy. Neither was his old man who won 4 cups and Conn Smythe because Claude made winning plays, despite a lack of skill.
BTW- I'd give Lems a look with right shots. Those passes would be easier to receive and tap in from the left wing. If you are double shifting Zibs, I would give Lemieux a look with him and Gauthier tell all of them to create space and go hard to the net. Zibs can demonstrate his leadership capabilities by teaching Lems and Goat how to cycle and get open. 3-man and 5-man cycles. Start with the 3 with these two. Then move to the 5.
