With the NHL's collective bargaining agreement set to expire on Sept. 15, the league proposed a new agreement to the Player's Association on July 16 and then entered three days of negotiations.

The one problem with this is that the deal appears to be weighted extremely in favor of the owners, with the league asking players to reduce their share of hockey-related revenues from 57 percent to 46 percent and eliminating salary arbitration, among other things.

Unsurprisingly, the proposal has not yet been accepted, but commissioner Gary Bettman remains optimistic that a deal will be made and another lockout will be avoided.
