And why would the NHL and Saskin be in Washington today, on a Sunday. How many federal mediators are going to go through the process on a Sunday? If the NHL has said it's "deadline" is Sunday night, it would make sense that they made it then in order to get any legal stuff done next week. I highly doubt that the NHL would be engaging themselves in that today rather than waiting by the phones for a call from the PA.
Besides, they have no rush to technically cancel the season once the deadline has passed, all Bettman has to do is come out and say see you in August...then the league has 5 months to get all the legal stuff done.
