Trade Rules
The Hawks are not in danger of being above the Luxury Tax (or its buddy The Apron) unless they make a series of moves that increases their Team Salary by about $15 million. We can safely ignore any issues arising from this and simply address the trade rules as such:
If the Hawks trade away up to $9.8 million in contracts, they can take back up to 150% + $100,000 of the amount traded away.
If the Hawks trade away between $9.8 million and $19.6 million in contracts, they can take back up to the outgoing amount plus $5 million.
If the Hawks trade away more than $19.6 million in contracts, they can take back up to 125% + $100,000 of the amount traded away.
The Hawks can always take back less salary if they so choose.
In addition, the Hawks cannot exceed the roster limit of 15 contracts. Not counting Cartier, the Hawks have 14 players under contract. It does not matter that Al Horford and John Jenkins are injured and out for the rest of the season, they are still contracts and they count against Atlanta's limit.
The Hawks are free to waive any player on their current roster to get around the roster limits. The Hawks will be liable for contract payments if the waived player is not claimed in the waiver process.
