Let's assume Horford signs. That's a lot of money to leave on the table. He could go someone else or OKC to pair with Durant but I still think he's absurd to turn down that contract offer.
Definate roster players- 8
Isaiah, Rozier,
Bradley, Smart,
Crowder, Jaylen
KO
Horford
Non roster players- 6
Mickey(possible roster)
Jackson(d-league)
Rj, Young(d-league or cut)
Yabusele and Zizic(overseas or called over)
Still decisions to make - 4
Sully
Jerebko
Zeller
Amir
players signed with other teams - 1
Evan Turner
Other free agents - ??
Howard
Durant
etc..
