Honestly, as someone who likes/is intrigued by personal stories/flawed personalities being explored more than I necessarily feel passionate about the spirit of competition/winning, count me in as someone who actually did feel that this aspect of Markus Naslund oddly made the game more fascinating to follow, even for multiple years (not sure what the hell "emo crowd" means, though). The struggle with emotional fragility/pressure (the fact that he was doing the best he could but his disposition is simply not built for leadership) added a dimension of drama/humanism to watching hockey that I typically don't get, and feels lost when everyone conducts themselves like an unflinching robot (or has the stereotypical "character player" qualities).
His solo dash game tying assist in the Calgary playoff series, for example, gave me a more explosive sensation than it would have if he were this mentally tough Trevor Linden type, personally.
I'm sure I'm in the extreme minority there, though. And I never got anything like that from Bertuzzi. As for Pettersson, sometimes I get that, sometimes I don't. When he initially had that struggle in his 70 point season, where he actually seemed to be trying (and making plays defensively) but everything was going wrong/his normally god-like instincts were suddenly failing him (you could feel the frustration through the screen), I did find that oddly interesting/engaging to watch in its own way. More recently, when he sometimes plays like he actually doesn't care, however, not so much.
He's so much of an impossible-to-understand enigma these days that it's tough to feel engaged in any direction. I'm just at a loss for what's even happening when he's on the ice.
