In order as far as minimum salary:
NHL, NBA, MLB...and NFL...with the NBA set to overtake that in the next year.
Not sure how that ended up being negotiated in the last rounds of talks, but I also believe that a max player in the NHL as also the lowest out of the big four. But as I said earlier...not really familiar with what the owners are claiming...and especially after they so resoundingly won the last talks. And from what I remember, the first offer from the owners a couple of months ago was so far out of the realm of reality, that it wasn't taken seriously.
