I get that, and it makes full sense. But a 15 game(exaggerated) losing streak is a dangerous thing for a young player. They have to develop maturity in not only their game...but in their attitude
We've already seen Pets display frustration towards his linemates. That is not good, and it is managements duty to temper that, as right or wrong as it is on the players part. It's a tight rope right now IMO
By all indications, he likes playing with Goldy and they're friends off the ice.
There just isn't any other talent to play him with. It's not the managing of the lines, it's just a bad roster. He and Bo are going to need to be on separate lines. And with Baertschi and Boeser out, there just isn't any talent left.
As for the winning argument, if you load up a Bo + EP line, you're really just conceding every other line to get caved in. Sure maybe you can get 22 minutes out of them. But that's 38 other minutes of looking at an absolute mess.
The Shotgun - EP - Goldy line actually has very good underlying metrics and decent production. It's the best shot we've got.
