We could get Jimmy Butler if he signs a Chandler Parsons like deal, forcing Bulls to trade him in year 2, and we may have a chance to sign him or Westbrook
The deal Parsons signed has an OPT OUT after year 2 and is a 3year MAX, that also owns a 1st year right and final say in a trade
Though eventually Butler could change his mind, especially if Derrick Rose isn't brought back and it does becomes Jimmy Butler's team, which was why he wanted to leave...
So after he OPTS OUT in year 2, Derrick Rose is also a UFA, and depending on how Tony Snell and Bobby Portis develop, along with Pau Gasol continues to play despite his age that also has an opt out next season, and what they will do with Noah/Derrick Rose could be interesting for a package deal..
