Hire a coach
Amnesty Tyrus Thomas
Draft Mclemore or Noel, both of them would have more than an immediate impact and would improve the team.
Don't resign Mullens or Henderson, sounds like Henderson knows he's on the way out anyway; this is what he tweeted on May 5;
"looking forward to what God has in store for me. not easy leaving everything I used to know behind but He will guide me...."
Starting lineup looks a little like this next year
PG - Kemba Walker
SG - (Ben Mclemore)
PF - (Paul Millsap, Josh Smith, maybe even JJ Hickson, Bismack Biyombo)
C - (Al Jefferson, Nerlens Noel)
