Trade & FA 2024-25:

I'm not sure what you were saying here, but 14,893,363 is the money that is left with 13 players accounted for, and DJJ is still unsigned. 

After subtracting 1M for an operating cushion, that leaves ~13.9M to allocate between some combo of DJJ (whose limit would be 12.9), the 15th slot, and a more-than-100% trade match.

Mavs salary for next season (THJ for Grimes trade already accounted) is 160.052 mil + 2.208 mil of McGee dead money, which is a bit over 162.2 mil. However, the allocations are calculated at 163.761 mil, so I assume there is one empty slot salary added to that. First apron minus 163.761 gives you the 14.89 mil space below the first apron. 

FA agent brought into that 14th spot would replace the empty slot salary, which means the actual available salary for the 14th guy is around 16.3 mil (this is the number Keith Smith mentioned). Take away 1 mil cushion and you are at 15.3 mil. If DJJ takes a couple of million below the max MLE, Mavs could get to over 17 mil of first year Thompson salary, if they only send Green out for air.

Everything will come down to how much Thompson and DJJ will want on their deals, but I can see a scenario where only Green is needed to make things work. 

Personally I wouldn't make Thompson my prime target, but this Mavs earned the benefit of a doubt for me.
