I know what I would have done:
I'd have drafted very differently: #14 Little, #20 Fernando, #22 Windler and #51 Jontay Porter
Sign Julius Randle for 80/4 (or a bit more). Trading Baynes I'm fine with. Let Rozier and Morris walk. Re-sign Wanamaker and Theis to small contracts as experienced bench players. Release Yabusele. We'd need an extra point guard, but not much cap space/exceptions left. Pick up Emmanuel Mudiay?
PG: Marcus Smart, Emmanuel Mudiay, Brad Wanamaker
SG: Jaylen Brown, Dylan Windler, PJ Dozier
SF: Jayson Tatum, Gordon Hayward, Semi Ojeleye
PF: Julius Randle, Nassir Little, Daniel Theis
C: Bruno Fernando, Robert Williams, Jontay Porter
Super young team, but at least we'd have added a lot of talent.
