Fix what is not working and provide stability.
Next coach should have a long contract, 5 years minimum, so he can quickly develop his own playing style with his own players and what is left of this trash roster.
Try to trade-cut vucevic, fournier byombo or whatever makes financial sense (maybe it is holding on to them for 2 more years, but I would trade them for picks or expirings, if any team would be crazy enough to take those useless guys.
The main focus should be develop youngsters like Gordon, Isaac and the next 2 picks and have financial freedom in 2 season so we can sign one good FA and maybe compete for playoffs in a couple of years.
