Yes. Anyone who has paid attention to the actual games and not the score sheets would agree.
It's an effort issue. He's never been a high end effort guy, but he's always at least looked like he gave a shit until this year.
The sheer amount of plays that die on his stick is mind-blowing. He's been a turnover machine and then doesn't put in the effort to get back. He has constantly blown defensive coverages, looks like he couldn't be bothered to stay with his assignment. He's forgotten how to hit the net, with consistency. It's either a goal or he misses by 5 ft. Just hitting the net helps the team as it causes rebound and chaos, but when you miss by 5 ft it does nothing.
His mentality has changed, and not for the better. He just wants to float and pick up easy points. Ismo was probably right with what he said.
