I originally had this as a longer thought out post but lost it when my computer shut down. So instead this is my abbreviated thought...
If the Cs fail to land the #1 or #2 pick and Horford is really looking to leave ATL.
FA
Cs sign Horford and his college roommate Noah.
In doing so they replace Sully with Horford and Amir with Noah. Hopefully the package deal is added incentive for Horford. As much as Noah was having a down year before the injury his rebounding and assist stats are crazy and both players are defensive upgrades or their predecessors. I expect Horford to command max money and Noah to be around 12-15mill.
Cs resign Turner if he can be had for a reasonable contract for a bench player (under 7mill per). If not let him walk and look so sign a Vet wing to fill the void (C Lee, G Henderson, Jared Dudley, alan anderson, Budinger, Rush)
Cs resign Zeller if he can be obtained for a reasonable 4th big man contract.
Cs retain Jerebko and let Amir go
Draft
Nets Pick, Dragon Bender: if needed use additional assets (Cs 2016, Mavs 2016, or ealrly 2nds) to move up and get him. Plan on leaving him overseas for at least 1 season.
Cs/Mavs picks: Package these and 2nds (and Young if needed) to move up in the first with the target being Timothe Luwawu. The more I learn about this kid I really like him. Great wing size/athleticism, plays tough defense and is developing his 3pt range. Seems like a better overall prospect then Hunter or Young.
If picks are left after trade target Nigel Hayes late first/ early 2nd
2016/2017 Roster (figure no turner, Sully, or Zeller)
PG IT, Smart, Rozier
SG AB, Hunter, Luwawu
SF Crowder, Dudley, Jerebko, Young
PF Horford, KO, Mickey
C Noah
if no Zeller the team would likely add a center as the 15th man. Maybe Colton Iverson gets a shot or maybe a journey man vet like Blair.
Given the improvement at the starting 4/5 position and the hopeful further development of the Cs under 25 players I think this team is a solid #2 in the east behind Cleveland. The mix of young and old with a potential star overseas in Bender would solidify this roster for a long time.
