I don't want it to happen, but between the rumored lowball contract offer over the winter (5x5 when he was pacing for 70 points), the comments about finding help for Eriksson Ek in free agency, the comments about Yurov being a center, the usage most of the year (when lineup changes were made, Rossi was the one moved down the lineup), and the usage in the playoffs, it seems like the coach isn't a big fan of Rossi's, and it doesn't seem like the GM values him all that highly either.
We saw this type of scenario play out with Fiala where it was clear the coach didn't really trust him, Guerin dicked around with the contract stuff, and then he was traded.
Guerin also mentioned he wanted a top six scoring winger, and there has been rumor and speculation that he's going to be active in trading this summer.
So that's why it feels like they're going tot trade him.
