Then Rudy, Ingles, Utah's 2018 2nd rounder and Trevor Booker for Alex Len, Devin Booker and T.J. Warren
Which leaves Wall, Favors, Burks and a trove of rookie contracts.
Wall / (Exum) / Neto / (Hanlan??)
Booker / (Exum) / Burks / Oubre
Burks / Warren / Grant
Favors / Lyles / Warren / Grant
Len / (Embiid) / Lyles / Withey
Thats 13 contracts signed thru next year. 5 thru 2018/2019. Jeff Withey would be the oldest 25 year old on the team. The average age would be near 22.
So the loss of the 2016 pick is minimal IMO. There's still 2 2nd round picks, and plenty of ammunition for them to fire at any specific target in the draft, if need be.
You've got a legit star in Wall. A stacked core of talent(too much to resign). Resigning Len and Embiid would be key but their both restricted and the other one being there is plenty of insurance.
