We can't have so much small ball, Crowder playing PF can be played many minutes, but not from the start. So if we can sign Hayward, which I also think we will, changes are needed.
My proposal for 2017-18:
This is too much supposition (which is needed to create a roster for next season), but let's assume we draft 3, our usual bad luck, fall to Cleveland in the ECF in six games and sign Hayward. We draft Ball because team picking #2 picks Jackson.
In order to round our roster, we trade Isaiah Thomas to the Pacers for Miles Turner and two second rounders. We need it after signing Hayward and drafting Ball to balance our team, and they need IT to convince Paul George to extend his contract.
PG: Smart, Ball, Demetrius Jackson
SG: Bradley, Brown, Gerald (minimum)
SF: Hayward, Crowder (Brown), Nader.
PF: Turner, Crowder, Amir (minimum), Yabusele.
C: Horford, Zizic, Mickey.
Our Minny 2nd round pick (38-40) is signed in a two-way contract with Red Claws, and Yabu + D-Jax are usually assigned to play in the D-League. Our two 50+ second rounders are stashed.
Olynyk is let go (a team offers him 20M per year) and Rozier is traded for a future first, lottery protected. Young, Jerebko, Zeller are let go.
Remember, defense wins championships. We are talented in offense and this roster would be a nightmare in D.
