Bruce Garrioch says that the NHL is going to try and keep the schedule as close to the one that exists as much as they can.
On January 15th, the day that a 50 game schedule would start, the Rangers are already scheduled to play the Islanders at the Nassau Coliseum.
If the NHL plays a 48 game schedule than the season will open on January 19th.
Madison Square Garden is available on January 19th. April 19th to May 14 is also open for rescheduled home games/playoff games/Knicks playoff games.
The league is expected to release more details on the schedule today/tomorrow.
