Summary
Coming out of college, Brown was seen as having some combo-guard playmaking potential, but that hasn't materialized in the NBA. Brown shows flashes of that playmaking ability, and overall shows a decent feel for the game, but just hasn't been able to put it all together. He fell out of favor in Washington, and was traded to Chicago during the '20-'21 season.

Brown's is a 35% career three-point shooter, but he doesn't shoot them at a high volume, and those have essentially all been spot-up attempts. Brown has changed his shot profile to replace most of his midrange attempts for threes, which is good considering he wasn't effective from midrange, but he's still not a great outside shooter either.

Brown finished well at the rim earlier in his career, but was dreadful in that regard in '21-'22, hitting only 51% of his attempts. Brown also just doesn't quite have the off-the-dribble creation ability to get there consistently.

The outside shot probably needs to improve for Brown to be a legitimate rotation-level wing. If he can get to average from outside, I think he could stick around as a wing that may not be great at any one skill, but good at a lot of things.

At 6'7", Brown has the size to defend multiple positions, and that malleability can be helpful, but he still needs to improve his play to warrant him getting consistent minutes. Brown is still only 22 years old, so he could be a decent "second draft" guy.
 
Cap Considerations
Brown will be a restricted free agent with a $15.5 million cap hold and a $7.2 million Qualifying Offer. If the Bulls do not have interest in bringing back Brown they could refuse to tender him a QO, making him an unrestricted free agent. With Brown's QO being above his market value, I expect them to not offer him the QO, even if they want to try to bring him back.

Other teams will have multiple ways to Brown as even teams without cap space could use any of the Non-Taxpayer MLE, Taxpayer MLE, or possibly even the Room MLE or Bi-Annual exception to sign him to an offer sheet or outright as an unrestricted free agent. He also could possibly be signed for the minimum.
