The salary cap will be at 62 million.
What we have on the books:
Draft pick 1.5
Draft pick 1.0
Total: 27.9 million
Then there's 1.2 M from Nick Young who has a player option, Elias Harris who has a .8 M team option and Nash who's owed 9.7M, that can be stretched 3 x 3.3 or perhaps retire - 0 million.
That's between 1.2 and 10.9 million added to the payroll, depending on what happens, taking it to somewhere between 29.1 and 38.8 M.
Before we start spending the difference, we have to account for the rookies - (a 1st and a 2nd rounder) which will cost about 2.5 as well as account for cap holds. Now it gets tricky.
Basically you have to decide what to do with each current player before you sign anyone else. For instance, Hill's cap hold is 6.5 so you either have to waive him, sign him for less or include 6.5 in the payroll.
Capholds: Blake, 7.6; Kaman, 3.8; Meeks, 2; the rest, 1 million.
So if you want to keep Hill, Farmar, Henry, Johnson and Meeks, you have to add 6.5+1+1+1+2= 11.5 in the salary, before you sign anyone else.
27.9 million in current salaries.
Up to 10.9 million depending on what happens to Nash and Young.
2.5 million in rookie deals.
Cap holds for the players we keep.
So what does it mean?
Best case, we keep Young, waive Harris, trade our 2nd rounder and Nash retires. Fill the roster with min cap holds - about 3 million total - and we'll have about 30 million in cap space. Best case.
If we keep Hill, it'll be 24.4.
Realistically we draft two rooks, waive Harris, stretch Nash and keep Nick Young.
Thats 27.9 + 2.5 + 3.3 + 1.2 = 34.9
We then keep Hill, Farmar, Johnson, Henry and perhaps Blake if he's willing to sign for 1 or 2 million. That takes our salary to 34.9 + 6.5 + 1 + 1 +1 + 1.5 = 45.9 million
And about 16 million in cap space to sign a FA or resign Pau.
