So more and more reports are coming out that it is not a hard cap set at 54 % of league revenues (divided by 30) but linkage that guarantees 54 % of revenues to players meaning the hard cap will be higher than 54 %. Which would rationalize the odd and contradictory math present in many other articles. It makes sense as that was what the NHL was going for with the payroll range of 51-57% etc.
If we assume they are projecting $1.8 bil in revenues a $37 mil cap is about 62 % and the floor would probably be around 40-45% (perhaps on the the lower end to take into account revenue sharing monies that lower revenue teams will be able to push up their payrolls).
Also note that the one known as Eklund despite being "wrong" on nearly everything else in the deal was the first to mention the Free Agency dropping through the course of the CBA in this manner. So he scores one point anyways for finding a legitimate rumour.
