When the NHL made the 1st offer, instead of a counterproposal arguing the points, Fehr came up with an offer that gives the players guaranteed raises while the owners might get something if the league revenues continue at 7%. It was nothing short of a partial rollback to the pre-lockout days and an attempt to divide the owners. Except for a few minor changes, he's entrenched in that viewpoint, much like the NHL won't let a union dictate how to run their business.
Fehr is like Goodenow, he's an idealist that believes unions should have a lot of power. He's not here to negotiate a deal, he's here for payback after the players lost the last round bigtime and I think he's filled the player's heads with enough water that if they hold out long enough and stay united they'll get what they want.
Unless Fehr gets removed, we might not see any compromise from the players, hence why the NHL is willing to cancel the WC and the season early on. They're just dragging things out, hoping for a split in the ownership.
