It's not rumors. Literally every single front office executive involved in hockey knows Chiarelli hated Slepyshev. I mean the guy publicly stated that he sent an email to every single NHL team that Slepyshev was available for trade, and of course other teams seeing Chiarelli say crap like this, know that we don't value him whatsoever, so they're not going to give any assets to get him and would rather give their own prospects a shot. Peter Chiarelli basically announced to the hockey world that we have no respect for this player whatsoever, and if your own GM doesn't respect you, other GMs aren't going to hold you in a positive light either, and as a player knowing that your GM thinks you're worthless despite you showing value via on ice play, and your coach would rather play a refrigerator on skates like Lucic despite you outplaying that buffoon pretty much every game of the season, you're not gonna want to stay either.
Peter Chiarelli is absolute cancer for this franchise. The tumor needed to be excised 2 years ago, but considering how our CEO is Chiarelli's best buddy Bob Nicholson, the imbecile running our team is going to ensure that this tumor becomes metastatic.
