Horford / Timelord
Giannis
Richardson
Smart
Schroder / Pritchard
If we still had Fournier, I might consider it. 
The spacing on that team makes me unwell (without a Fournier-type)
my thinking too. they'd make noise in the East but unless Pritchard, Nesmith and Romeo all develop significantly going into the season where they're hitting outside shots consistently, they're not winning it all.
So you have a down year where you only win a round or two in the playoffs and then you regroup in the summer with the best player in the sport who is signed long term. Not a bad place to be.
And I do think they'd have a shot (the trade with the enough salary that is the simplest to do is Giannis/Connaughton for Tatum/Brown).
PG - Schroder, Pritchard, Dunn
SG - Smart, Connaughton, Langford
SF - Richardson, Nesmith
PF - Giannis, Parker, Williams
C - Horford, Williams, Kanter, Fernando
cut Edwards
I think that team would have a real shot this year, but would be in pretty good shape next summer with Horford and draft picks available to acquire a better running mate for Giannis.
If you can acquire the best player in the world, you have to. Every time, without question.
