The Chicago Bulls will be busy in the offseason and the fans at the United Center could sway them to make changes from bottom-up. Chants of "Fire Fred Hoiberg" were heard after the Bulls were eliminated by the Boston Celtics.

Fred Hoiberg understands the frustration that led to the "Fire Fred Hoiberg" chants and Bulls management is more than likely to take his side. Seeing how the former Bulls player was handpicked for the job, the actual work to be done will actually be the roster for next season according to NBC Sports.

Who stays, who goes for Chicago Bulls

The fate of Jimmy Butler, Dwyane Wade and Rajon Rondo vary and a previous post reveals why all three are likely to remain with the Bulls next season. Butler expressed his desire not to be traded and Chicago may just pick up the team option on Rondo.

And while Hoiberg and Butler hope to bring the same roster back next NBA season, it may all depend on Wade’s decision. The all-star guard has a player option where he stands to earn US$23.8 million (AU$31.3 million). At his age, “The Flash” may not get a higher offer thus higher chances of returning next season.

Can Hoiberg live with the heat?

Assuming that Hoiberg stays one, expect Gar Forman and John Paxson to keep a close watch. While it is true that Hoiberg is someone they coveted to replace Tom Thibodeau, results still count.

If the Bulls "Big Three" does return, the Bulls may need to get more players to help out. They do have a group of young and promising players but toughening up front is a need.

Chicago Bulls need more enforcers

Since parting with Joakim Noah and Taj Gibson, the Bulls have lacked blue chip workers who can mix it up inside. Nikola Mirotic, Robin Lopez and Bobby Portis have tried to fill in that need. However, something is still lacking.

The Bulls don’t need a big man that can score. They need a rim protector and someone who can help control the boards. The Chicago Bulls could revisit a possible deal for Jahlil Okafor of the Philadelphia 76ers or maybe someone else.

Among the top NBA free agents listed by Hoops Hype, the Bulls could look into the possibility of several players like Blake Griffin, Paul Millsap, Ersan Ilyasova and Zach Randolph for the forward position. If they want to fill up the middle with a proven big man, Greg Monroe, Nerlens Noel, Mason Plumlee or JaVale McGee could be worth a look.

The Bulls can also evaluate the new talent from the 2017 NBA Draft. The incoming pool is expected to be deep so plucking one from the new breed may be an alternative.
