The luxury tax is destructive. Few teams can afford to pay it. Look at what some of you are suggesting. You've got the Celtics with a payroll + cap penalty greater than the team's revenues. There's no way the organization would do that. Not even the Knicks would do that.
It's killing some of you, but pretty much our only reasonable course of action is patience, unless an Anthony Davis or Kevin Durant somehow becomes available.
Not only is the luxury tax destructive, but players/agents/teams/fans went completely of the road to what 'normal' salaries are. The players that signed big contracts the last two years are not overpaid. They are severely overpaid! They took all that money that was flying around and the next group of free agents are the ones who will pay for that. Maybe not this summer as teams still seem to be struggling to make rational decisions, but certainly in 2018.
Because of the luxury tax teams can't maintain a super expensive roster like the Lakers, the Heat or the Nets had in previous years. So I looked at what common salaries were for contenders in the past that had a reasonable team payroll. I took the season of 2012/2013 because the cap had been stable for years and no big cap explosion was to be expected. During those years the cap was around 60 million and the projected salary cap for upcoming years seems to be around 110 million. So let's take those salaries from 2012/2013 and multiply them by the factor 110/60=1,83.
Examples:
Chicago BullsDerrick Rose
*injured (star) 16.4 => 30.1
Carlos Boozer (starter) 15 => 27,5
Luol Deng (star) 13,3 => 24,4
Joakim Noah (star) 11,3 => 20,7
Richard Hamilton (role) 5 => 9,2
Kirk Hinrich (6th man) 3,9 => 7,2
Taj Gibson (role) 2,2 => 4,0
Marco Belinelli (role) 2 => 3,7
Jimmy Butler (starter) 1,1 => 2,0
Nate Robinson (role) 0,9 => 1,7
Rest 3,3 => 6,1
San Antonio SpursManu Ginobili (6th man) 14,1 => 25,9
Tony Parker (star) 12,5 => 22,9
Stephen Jackson (role) 10,1 => 18,5
Tim Duncan (star) 9,6 => 17,6
Boris Diaw (role) 4,5 => 8,3
Tiago Splitter (starter) 3,9 => 7,2
Matt Bonner (role) 3,6 => 6,6
Danny Green (starter) 3,5 => 6,4
Kawhi Leonard (starter) 1,8 => 3,3
Cory Joseph (role) 1,1 => 2,0
Gary Neal (role) 0,9 => 1,7
Rest 3,8 => 7,0
Oklahoma City ThunderKevin Durant (star) 16,7 => 30,6
Russell Westbrook (star) 13,7 => 25,1
Kevin Martin (6th man) 12,4 => 22,7
Kendrick Perkins (starter) 8,3 => 15,2
Thabo Sefolosha (starter) 3,6 => 6,6
Nick Collison (role) 2,9 =>5,3
Serge Ibaka (starter) 2,3 => 4,2
Reggie Jackson (role) 1,2 => 2,2
Derek Fisher (role) 0,3 => 0,6
Rest 6,8 => 12,5
So after the adjustment all the teams have only four players that earn over 10 million! Every player that earns 6 million or more is at least a very valuable role player or a starter. And if you pay a player a contract over 20 million it needs to be a star/superstar if you want a good return for your money. If we ignore the rookie contracts, then we can see what are reasonable salaries to be paid for the role on the team you want your player to be:
Average star/superstar: 13,4 => 24,5
Average starter/6th man: 7,4 => 13,6
Average role player: 3,2 => 5,9
As we can see the stars are generally maxed out or at least close to that. We see that regular starters or sixth man (on a contender!) would be paid around 12 to 15 million. Then there's a big drop off. Valuable role players who play around 15-20 minutes a game only get paid 6 million on average. It was and will be a star driven league.
The reason that Cleveland and Golden State are able to afford their stars in the short term is because Irving, Curry, Thompson and Green are now underpaid because they signed their contracts under the old salary cap. And they're already maneuvering in very tight spaces, so to speak.
In the future no team will be able to keep such loaded rosters as the Cavs and Warriors, unless players are willing to take paycuts. The Celtics have no stars locked up for cheap, so we really have to be patient so we can anticipate on the mistakes other teams make and profit from that.
So if we discuss what salaries we want to pay for our upcoming free agents. Please look at what you should expect in return for that. If we pay Olynyk 12 million, then you can't be satisfied with a role player, but you'd need to expect that he can at least be a 6th man. Same goes for Smart, if you pay him 15 million and want to compete, then he has to be able to be a good starter. And a 20+ contract for Bradley means that you're convinced that he's a star in this league.
