The N.H.L. made a surprise offer in talks for a new collective bargaining agreement on Tuesday in Toronto, proposing a 50-50 split of hockey-related revenue with the N.H.L. Players’ Association and a mechanism guaranteeing that current contracts would be honored without rollbacks.
It was the first significant movement in the negotiations since the league’s owners locked out the players Sept. 15 and subsequently canceled the first two weeks of the season.
