If the player wants out, and he does, then it's not in poor taste. It's facilitating a deal, which is what BUF, Eichel and the prospective team wants. It's especially important, because as Friedman reported... while Eichel is skating, it's still believed he needs surgery. It's rather hard for teams to give an offer if a pretty important piece of info is missing.
It's ridiculous to say "Give us your best offer for a healthy Eichel and then we'll let you see info and if you don't like it you can opt out." It's simply not the way other teams do business.
