I've been saying $12-14 million, but more likely $11 million than $15 million if it's outside of that range.
I think whether he stays depends somewhat on other moves this summer. If we sign Blake Griffin, good-bye KO. But if we sign Hayward, I think it's much more likely Bradley gets traded and KO is resigned. Remember too he has a cap hit this year of $7.75 million regardless of what he signs for, so if the deal isn't too expensive, moving him in the future is an option if his salary gets in the way of something. Brooklyn took on three years, $20 million of Andrew Nicholson for a late 1st, and sent back Bogdanovich as well. Nicholson a DNP-CD type, and Olynyk is if nothing else a legit rotation guy.
I think Olynyk stays at anything up to $14 million (unless Blake signs here) and I still think that's his ceiling. So I expect to continue to see Olynyk in a Celtics uniform in the future.
