Why are the Bulls' F/O so interested and willing to give Fred Hoiberg the coaching job?

I mean if you look at it, firing Thibs at first glance seemed completely nuts and dumb to most but if you dig deeper you could tell it makes sense....Thibs was a great coach but was too stubborn and would not lead a team to a championship overall. Despite his capabilities to turn the Bulls around numerous times the past years without Rose. But Fred Hoiberg of all people...seems like the F/O just knows him really well with the Iowa connection between him and Forman...or they just want a cheap guy that they can control....or perhaps just dumb? Nothing against Hoiberg but to call up a college coach after firing probably one of the best coaches in the NBA as your first priority for the job is just nuts to me.
