Hoiberg was in his fourth season as coach of the Bulls, logging a 115-155 record during his tenure.
Seeing that the league was shifting more towards the perimeter, Chicago chose to bring in former college coach Fred Hoiberg.
Before the dust could settle on the Chicago Bulls' historic defeat against the two-time defending champion Golden State Warriors, a message was written on a dry erase board inside the coach's office of the United Center's home locker room. "After a thorough evaluation, I elected to make this move with the overall development of our team in mind", Bulls executive vice president John Paxsonannounced in a statement Monday morning.
In his place, the team has elevated associate head coach Jim Boylen to head coach effective immediately. "I want to thank Fred for his dedication and efforts, as well as for his enduring commitment to our team".
The Bulls fired Hoiberg after a 5-19 start to the season, including nine losses in their past 10 games.
The Bulls are a relatively young team this season but have seemingly been going backward of late, losing six straight games.
The leader at Iowa State for five seasons, Hoiberg's preferred style of play fit perfectly with where the National Basketball Association was headed: plenty of 3-point looks from everyone on the court with an emphasis on pushing the ball in transition in order to generate open shots.
Boylen was hired just a few weeks after Hoiberg in 2015, and has a lengthy résumé that includes more than 30 years of assistant coaching jobs in college and the NCAA. Additionally, he has coached collegiately at Michigan State, where he served on the staffs for both Jud Heathcote and Tom Izzo.
