I wonder if the weather's going to cause them to cancel the Bruins game tomorrow. So far, it looks like snow starting in the Boston area at around 11 PM, 1"-2" per hour for 6 hours. Rescheduling would be close to impossible: the Bruins bye week is from 1/20-1/24, followed by the league shutdown on 1/25-1/27 for the ASG. On 1/28, the Garden is booked by the Celtics. Rest of January is filled if you want to avoid 3-in-a-row.
Assuming we want to avoid 3-in-a-row, 4-in-5, ridiculous coast-to-coast-to-coast travel, and domino effect scheduling:
February availability for the Bruins is 2/1, 2/24, and 2/25. And 2/22 I guess, if you want a Vegas-Boston-STL flight pattern. The Garden is booked all of those nights (Eric Church and Disney x2) except for 2/25, and 2/25 causes a 3-in-a-row for the Rangers.
March isn't better. Bruins have 3/3, 3/4, 3/17, 3/18, and 3/28 available. Rangers can't do any of those dates without a 3-in-a-row or 4-in-5.
April won't work on any day for the Bruins until 4/7, which would be the day after the regular season is scheduled to end. (We did this exact thing last year.) But even that's no good for the Rangers - the earliest possible game would be Monday 4/8, with playoffs for both teams probably pushed to Friday when they'd normally start on Wednesday/Thursday.
Of course, they can break rules: maybe there's an easy way to shift one game to make an opening. The Celtics were flexible last year in moving their game so we could play our season closer. And 3-in-a-row isn't unprecedented - I think Carolina and/or Detroit had to do it when there was an ice problem at an arena. But both teams got the 3-in-a-row, so it was fair.
But it'll definitely make them more hesitant to cancel the game. It's a big NYC-BOS moneymaker on a weekend - outright cancellation will make many people - fans and owners - mad. That said, if the weather's bad, I do hope they cancel it.
