I don't think ersan is as good as he was this year, think the short schedule may have helped some shooters, as it gave teams less time to prepare and made them more tired and less willing to close out shooters
However ersan is young and quite productive and if kg accepts around 9 million then we should be able to offer ersan 8-9 mill .
If they did and bass opted in, they would probably have 3 mill left to offer another free agent. I think bass might opt in on the promise of an extention for following years which they should be able to offer.
They could also use up to two 2.5 million dollar exceptions (rooom and bi annual). If they signed a free agent using cap space.
To resign greg, green or allen they would have to use left over cap room or the exceptions, as they would need to renounce bird rights to create the room to sign a free a major free agent (Btw they don't hold greg birds rights anyway).
The other free agents that intrigutes me instead of ersan is g wallace. He would be great as undersized four next to pierce and they could use him to guard elite 3's and give pierce a break. He would also be great running the floor with rondo. I read somewhere that the nets wanted to sign him for 3 years 24 million, can't see why couldn't do similar deal.
