Not sure it makes sense to weaken the powerplay or top 6 just to feature somebody that you are trying to trade. They're trying to win games, not marginally improve the return on a depth player who isn't carrying his weight.
I fully agree. My point isn't to "weaken" any aspect of the team, especially not to try and trade someone.
My point is more than they've kind of created this self-fulfilling prophecy with many of these controversial players.
Controversial player has decent (or in some cases, very good) per-60 stats.
Controversial player ends up lower in the line-up, playing with less talented linemates and with zero powerplay time.
Despite controversial player producing well in the ice time and situations they get, their total boxcar stats aren't overly impressive.
Unimpressive total box cars are used as justification to push player further down (and then eventually out of) the line-up.
It's a domino effect that we've seen play out a few times now.
For emphasis, Anthony Mantha has less powerplay time in 42 games this season than TJ Oshie has in 25 games. Sonny Milano, in the 29 games he's been in Washington, has passed Mantha on the PPTOI charts as well. In the 4 games Connor Brown played for Washington, he got 1:37 PPTOI per game, compared to Mantha's 0:55 per game this season. Dmitry Orlov, who's essentially the #3D on the PP depth chart on a team that only runs 1D at a time per unit, has more PPTOI per game than Mantha. It's not just the Ovie's, Kuzy's, or even Carlsons and Stromes ahead of Mantha on the depth chart - it's an assortment of other middle six and complimentary players like Marcus Johansson and Conor Sheary. There are stylistic arguments to be made to justify specific players, but it's pretty easy to see why Mantha's overall stats are suffering when the coaching staff is prioritizing all sorts of other players over him.
