With the delayed start of the season until at least January, does the deadline for RFAs to sign stay at the 1st December or is it moved to an equivalent date a similar % of the way through the delayed/shortened season?

Good question, i think we will know at the same time as the NHL announces it's plans and changes

You’d have to think that they change it, or maybe even remove it altogether this year. I also wonder what would happen with salary cap calculations if when the season ends is up in the air.
