According to NHL Insider Elliotte Friedman, that $80 million salary cap could come a lot sooner than anyone thought. Friedman says that it could happen as soon as year six of the current CBA, or the 2017-18 season. For comparison, Mirtle's 5 percent projection estimated a cap of $71.8 million that same year. The cap is currently set at $64.3 million for next season with a floor of $44 million.
If Friedman's $80 million target is correct, that means the salary floor would hit about $55-60 million at that time. Under the new CBA, the cap ceiling and floor are calculated by adding/subtracting 15 percent to the salary midpoint.
