Using Hoopshype numbers:
Current salary: $135,515,880 (accounts for Kanter and Parker)
Tax threshold: $136,606,000
Tax apron: $143,000,000
Room under apron: Approx $7.48 million
Full MLE: $9,536,000
So, if those numbers are right we are just about $2 million away. The easiest way to achieve that would be to cut Jabari Parker and his non-guaranteed salary. However, that would seemingly leave a roster hole.
