I don't even care as much about the body language. It's the not pushing the play that gets me. Like I get if that's just his personality. As long as he's trying to make things happen on the ice and making use of his talent then he has every right to be who he is and exhibit whatever body language comes naturally (though good body language is generally just better, especially in a team environment). But he doesn't. His play, while intelligent and responsible, is just so vanilla offensively.
I said it last season during the playoffs: I think it's actually more simple than we all think. The guy just needs to get stronger. He's lacking confidence to impose himself out there and I honestly think something as simple as getting stronger, staying on his skates and being better able to hold on to the puck and cut to the middle and bulldoze through or around defenders would help his confidence tremendously. The floodgates would open. That's how confidence works.
I genuinely feel for him if all the noise is getting to him. It's a tough situation because it's not as if the market is being unfair either (talking in general, obviously there are always idiots out there who say terrible things). I just hope he can be assured that the entire city is pulling for him and has his back. Hell, that should be abundantly clear after the playoffs when the fans tried to get him going. Like, the market is quite aware of exactly how he's struggling (mentally) and tried to give him a pick me up.
He really doesn't have many excuses. He's just got to figure it out fast. And the organization should be helping him in any possible way they can.
