Last Saturday, NHL owners locked out players (who knew?) following expiration of their contract. The last strike, in 2004, wiped out an entire season and players ultimately agreed to a 24% rollback, reducing their take to 57% of revenues. Owners are now demanding a further 17.5% rollback to 47%. Players are unwilling to concede much and owners expect to get their way, again. This will be a very long strike.
