Let's not get carried away dumping on JT. I just looked it up, he was tied for 64th place among forwards in scoring this season, with 32 teams in the league, wouldn't that mean he's still a 1st line forward? Plus he's dependable defensively, strong on the boards and on faceoffs, he was basically Crosby lite so maybe now he's Crosby extra lite but still, a 1st line forward who's strong defensively, that's a valuable commodity and far from someone who's holding Marner back.
Marner played like crap these playoffs, and that's on him and nobody else.
