#91 from Coon's Salary Cap FAQ
For example, if a player on the last year of his rookie scale contract earns $5 million in 2018-19, and his contract is extended for four seasons starting at $10 million, with 5% raises, then his salary in each season will be:
Season Salary
2018-19 $5,000,000
2019-20 $10,000,000
2020-21 $10,500,000
2021-22 $11,000,000
2022-23 $11,500,000
If this player is traded during the 2018-19 season, then his outgoing salary from the sending team's perspective is his actual salary -- $5 million. But the player's incoming salary from the receiving team's perspective is $9.6 million -- the average of all five seasons. Such a player would be very difficult to trade -- a legal trade can only be accomplished if both teams add additional salary to the transaction, or if they include a third team that is able to absorb excess salary.
I already quoted from Coon, question 101 about when players can not be traded. These override the Poison Pill Provision. A trade with a PPP can only take place after waiting the 6 months.
If Brown signed his extension in early July then in January he could have been traded using Poison Pill Provision rules, but he signed his extension in October which means he can't be traded until after the trade deadline or until the Celtics season ends. If the C's don't make the playoffs, then between mid April(season's end) and July 1st, Brown could be traded using PPP rules.
The ESPN trade machine will tell you if the player can't be traded or when the player can be traded.
Right now you can trade Jaylen or Sabonis in the ESPN trade machine.

You have to understand that ESPN and RealGM are in the business of sports.
They do that for a living.
So in this case I would prefer to believe the professionals.
Your own citation for how Jaylen’s trade would work means that his incoming salary to another team would be counted as $22.6 million incoming salary, correct? 4 years at $107 million (this excludes his unlikely bonuses but includes his likely bonuses, per other trade rules) averaged with the $6.5 million he’s making this year, for a total of 5 years, $113.5 million, or roughly $22.6 million. Do you agree with that?
I'm just pointing out that Brown can still be traded.
Here's why the PPP doesn't fall under the 6-month rule, right now Brown is still on the last year of his contract.
Brown's new contract will take effect July 1, 2020.
So technically, Brown is an expiring contract.
It just so happens that Brown and the Celts already agreed on a contract extension for July 1, 2020.
Look at the list of players that can't be traded this season.
