I don't want to get rid of Smart or Brown because I love watching them play. I really enjoy the way Smart plays the game and I think Brown is the kind of electric athlete and scorer that we've been missing for a while.
I'm okay with trading away Bradley, Rozier, Olynyk, or pretty much anyone else (except for Crowder) and future picks to get a star. That said, the 2017 class has been highly touted for the last 2.5 years, and the 2017 Nets Swap looks to be particularly valuable. If there's such generational talent available in 2017, I'd be hesitant to trade away that swap. For example--if we trade 2017 for Boogie at the trade deadline, worst case scenario is that we get 1.5 years of Boogie and lose out on 8+ years of the next Superstar payer.
If I'm Ainge, I'm telling people that they can pick 4-5 of any of the following for an all-star:
IT, Bradley, Rozier, Olynyk, Mickey, Hunter, Yabu, Zizic, 2018 Nets 1st, 2018 Celtics 1st, 2018 Griz 1st, 2019 Celtics 1st, 2020 Celtics 1st.
If that's not enough to get it done, than fine. We're in a great position to go forward with what we have and develop our young players.
