If I remember, Zaire Williams was a high risk high reward type...he's already seeing minutes and shooting well it seems.
If he is mature in that he can do all the little things on the court in big games, then they might as well keep him as he could become their SF of the future..
Morant, Melton
Bane, Brooks
Z. Williams, Brooks
JJJ, Clarke
Adams
If Memphis doesn't value Zaire W. that highly then Sabonis would be a great get....but agree with Roy, unless he's happy coming off the bench it could create issues....He'd be an awesome first big off the bench 6th man ala Kevin McHale
