I read that JR might opt out and look for more. Looking at next year, they have:
$21.6 James
15.9 Irving
9.6 Varajao
6.8 Thompson (QO)
5.0 Mozgov
1.1 Dellavedova (QO)
0.8 Harris
===============
$60.8 subtotal plus holds for six roster spots puts them around $63.8 million. That assumes JR and Mike Miller both don't opt-in. I imagine Miller will at the very least. With a cap just over $67 million, they almost certainly will operate over the cap and just have the MLE.
Haywood's contract would allow them to do a sign-and-trade for almost anybody given it's non-guaranteed pre-8/1. That's their ace in the hole - $10.5mm outgoing contract.
