I’ll be honest I don’t like Ehlers and Perfetti together. Ehlers plays an unpredictable game which is hard to read off of. I think Perfetti works best when players are where they are supposed to be in the attack zone.
I agree on Ehlers game - he is unpredictable
I'd also say that many/most players struggle when playing with that type of player - so moving him is not really the answer IMO (although I understand the point, just not necessarily the solution).
I think the onus is on Ehlers to adjust his game to better suit the systems and his linemates - that won't be easy because he has always played pretty loose out there and not necessarily using his linemates as much as most players would. He's a possession player who likes to carry the puck - maybe a bit too much.
Coaching needs to step in and work with him - and maybe they already have which might lead to why he is sometimes seeing reduced minutes.
He might be struggling with changing his game. I assume the team will continue to work with him on this - and we'll need to be patient. But at some point, they will expect him to adapt.
I'm watching his game a lot lately - and it looks like he is trying to shift his game a bit. He is not hanging onto the puck as much as he was - and he's trying to make more plays (or be in a better position to be part of the play) - but you can tell he is still learning how to play this way.
His passing is off - he is still waiting too long to make the play. Without the blinders on, he might be having some difficulty reading / digesting the game and his options. Things become a lot more complex when you are expected to keep an eye on your linemates and the defenders, anticipate, and make plays. For a guy that has done it on his own most of his career, this has to be a huge change.
Hope they can sort it out - he has all the skill to be a huge asset to any line he plays on - coaching will play a significant role in transitioning his game.
