If hockey used the luxury tax

A lazy way to go far over the cap.

What are the details of your luxury tax?

if hockey had that teams like the leafs would have an unfair advantage. They can afford it, while many teams in the league cant.

The way I personally want it to be is that every team can make one player cap-exempt, but once made cap-exempt at the start of the season they cannot be traded.
However, if a team chooses (or cant afford) not to use the marque then then they are awarded compensation picks. It could look something like:
-100% of 13m used: 0 picks
-75% of 13m used: Additional pick at the end of the 4th round
-50% of 13m used: Additional pick at the end of the 3rd round
-25% of 13m used: Additional pick at the end of the 2nd round
-0% of 13m used: Additional picks at the end of the 2nd, 3rd, and 4th rounds
Picks cannot be traded

Not only does it compensate low budget or rebuilding teams, but it allows for more players to be drafted which is better for the game as a whole and allows for players from non-traditional countries to be drafted, similar to Kirk last year.

I know it's not a Luxury Tax, but I think it would genuinely help the game.

We all know the leafs would also sign Hall for 20mil and Piet for 18 mil

They'd sign the whole league
