I don't think any of them other than Trouba maybe, are embarrassed. Their "meh" attitude comes right from the top down. Chris "I won't let it ruin my weekend" Drury is such a drab milquetoast person. Gallant has no personal accountability. Panarin shows up when he feels like it. Mika is either in his own world or focused too much on his flow. Same rotten issues that plagued this team months ago still exist.
I really wish these players would read these boards to see the things their hard working fans are saying about them. Fans that spend their hard earned money and time watching the games as a form of entertainment to escape the everyday grind. Maybe they'd self evaluate feel some kind of embarrassment. And then actually show up to the rink and put an honest effort in.
Yes, Gallant should never have moved Mika off that spot. He's the only one who actually regularly looks to unload a shot on the PP and that is his most effective spot.
