If you're asking, can we in accordance with the CBA, yes, definitely I think. He's our own guy.
This coming year we should be fine even if we do go into the LT some. Hopefully we can dump Burks and opt out of Diaw or at least get him on a cheaper deal, and maybe dump Lyles.
In 18/19, we currently only have have:
Gobert--22.74M
Burks--11.54M
Lyles--3.37M
Bolomboy--1.54M
...along with cap holds...
If we dump Burks and Lyles, that gives us Rudy and Bolomboy at 23.28 total. Let's say we stand pat and have our 2017 24th and 30th picks on the roster that season. That's 1.56M and 1.38M more per RealGM. So for four guys, that's 26.22M. Let's also assume we have our two 2018 NBA 1st rounders on that roster and that they are the 21st (OKC this year) and 24th picks (same for us again) and that the rookie scale goes up a little. That's 1.77M and 1.56M more for 3.33M more total, now putting us at 29.55M for six guys.
Let's say Hill is at 25M, Hayward 37M, and Ingles 12M. Now we're at 103.55M for nine guys. Gobert, Hayward, Hill, Ingles, Bolomboy, our two 2017 1st rounders, and our two 2018 1st rounders. If we can retain Favors, Hood, and Exum for about 15M each (wishful thinking), we'd then be at 148.55M for 12 guys. We would probably have 1-2 2017-2018 2nd rounders on that roster too, along with maybe 1-2 cheap vets, putting us at around 155-160M.
So yeah, again, per the CBA, I think it's possible. But looking at these projections, unlikely. All the more reason to try to keep Hill somewhere more around 22M. Ingles more around 10M. And if we can, we may be able to retain two of Exum, Favors and Hood. And pray the Cap/LT actually end up going up a little next year.
