Should the Bulls trade down or keep their #4 pick?

There are a handful of teams that seem to be expecting 2020-2021(who also have lottery picks) to be an excellent year to rebuild considering the shortened season. Teams that are definitely not in win-now mode(like the Bulls want to be) and who could lose their starters to free agency or sign & trades. Teams like the Kings, Spurs, Cavs, Pistons & Knicks.

There's always talk of the Bulls taking the big risk and going for All-Stars like Giannis or Ben Simmons, but it seems more realistic to trade down to a different lottery spot to get a win-now type of player in exchange for a pick and one of the Bulls revolving starting 6.

But then again, should the Bulls take the risk on high upside guys like Avdija, Hayes or Toppin?

What do y'all think?
