My concern isn't the results but the intensity, which, as noted is non existent. If he looked like he was out there trying to make a mark on the games, i wouldn't have any concern. He's on the 3rd line, with young guys, and not getting much time on the PP. So, i dont really care about his points.
The last game against the Kraken i saw him throw a couple hits early in the game and thought to myself, "oh, maybe he's looking to get involved somehow". But that ended up basically being it. He had a couple good passes that didnt end up going anywhere mostly because his wingers are third line guys. But he spent the rest of the game coasting and falling down. He has got to find a way to make an impact on the game. It doesn't have to be points, but it needs to be something.
My direct comparison would be Byfield last season. Most everyone was concerned about his production. Oh, he only has 3 goals, he's a bust. But if you actually watched the kid play, you saw somebody who was working hard, and finding ways to impact the game in a positive manner, even if it didn't lead to personal accolades. He was moving his feet. He was getting to loose pucks. He was winning battles. He was fighting to get to the dangerous spots on the ice. PLD looks like the exact opposite. He's not winning his board battles. He's coasting into engagements. I rarely see him fighting to get to dangerous areas. He's floating.
He may still be trying to find his fit on the team as a guy who is used to top line minutes and PP time. I do not believe it's anything to do with adjusting to the system. It's a role issue, and a fit issue, and he's not doing much at all to help in that regard. I can see how this would be a big change for him, and i can see how it would be tough on anybody used to being a top guy, but he's got to figure it out, and the team needs to find ways to help get him engaged. You simply cannot ride the season on hoping he somehow turns it up in the playoffs. That's not good enough.
