My ideal team is something like (and while I think this is realistic, it isn't all that likely)
3 Team Trade
Pelicans acquire - Tatum, T. Johnson, Yabu, Memphis, 6
Suns acquire - Smart, 14, 22
Celtics acquire - Davis
Draft high risk high reward player at 20 (maybe Clarke, Bol, Johnson, etc. - i.e. someone that falls)
Opt-in or Re-sign - Horford
Re-Sign - Irving, Morris, Baynes
Sign - Rubio (MLE), Vet Min. SG (Carter, Rivers, Clark, Brewer, etc.)
So team
PG - Irving, Rubio
SG - Brown, VET FA
SF - Hayward, Morris
PF - Davis, Theis
C - Horford, Baynes, Williams
with the rookie, Semi, and others like that in the GLeague or deep bench
