As a leafs fan, would love to see this happen. Salary caps are so tedious, its just wrong that great teams like Chicago and LA have to get worse just because they did a good job drafting and now cant afford all the players they acquired
Remind me again how Chicago was able to get such a talented roster?
Oh that's right, they were handed high draftpicks that landed them Kane, Toews, etc.
The salary cap, just like the draft, is simply part of the system. You cannot complain about the disadvantages of the system (losing players because of the cap) when you got your best talent because of the advantages of the system (through the draft). There is nothing unfair about it.
After their first Cup, Chicago had to get rid of some good players because of the cap. Some people complained, completely ignoring that Chicago decided to spend a ton of money on free agents prior to the season. If they had wanted to keep all their own players, they simply shouldn't have signed these free agents. But that may have meant that they wouldn't have won the Cup. They made their decision and had to live with the consequences, both good (winning the Cup) and bad (losing good players). Now they are in trouble because all their great players cost a lot of money, again, it's their decision to pay them so much, they could have refused, and the players could have asked for less. Not to mention that the fact of them gaining their best players because of being handed high draftpicks still remains, thus leaving them with little reason to complain about the system which benefitted them a lot.
As for the original question:
Hopefully never. The luxury tax is a horrible idea, especially compared to a hard cap. It does absolutely nothing for the league.
