The only way I'd do that is if we traded something like number 1 and Bradley to Philly for Simmons and number 3, which I still think is a slam dunk deal for both sides. Then I'd trade number three, the 2019 Clippers pick, and Rozier to Chicago for Butler and Portis. That'd leave you with the following lineup:
PG: IT, Smart
SG: Butler, (perhaps Green on the minimum contract)
SF: Crowder, Brown (though hopefully Brown would take the starting spot by the end of the year)
PF: Simmons, Portis
C: Horford, Zizic
I love the look of that team, and the small-ball lineup capabilities are ridiculous.
Otherwise, I'm completely fine taking Fultz and then trying to sign either Griffin or Hayward in free agency.
