The NHL salary cap is expected to rise to about $71 million next season, an increase of more than 10 percent. NHL Commissioner Gary Bettman made the optimistic announcement Monday at the league's board of governors meeting. The ceiling of the salary cap is determined by hockey-related revenue generated this season, so the new figure is merely an estimate, Bettman said.
''I said to the board there shouldn't be any issue or consternation,'' Bettman said. ''If that's the cap level, it's because the revenues have gone up. We try to give people a sense of where we think it'll come out.
''It's subject to a whole host of issues, ultimately how much revenue is generated, where the Canadian dollar is, because we convert to U.S. dollars. If you want a rough, rough, rough ballpark, OK, but it could change.''

And this doesn't include the new broadcast deal in Canada, which effect won't be felt until the 2015-16 season.
