I’m quite surprised with the sudden vigor and enthusiasm the Bulls have played with on the defensive end as of late. Their rotations and effort seem so much better. Why couldn’t Fred Hoiberg and Jim Boylen have had more of a synergistic approach for the sake of the team? Now that Fred is gone, you can clearly see the offensive struggles yet you have improvement on defense. Which makes one wonder: Was there an ulterior motive by Boylen to supersede Hoiberg? Where was this defensive accountability when Fred was here? Jim was touted as a defensive guy with loads of experience and given associate head coach status. Was he not given a voice to implement his schemes? Or did he keep them close to his chest as a choice? I believe in the roster Gar (Forman) and (John Paxson) have assembled. I understand a few more pieces are needed, but the core four is a great foundation. It’s just too bad Jim and the previous coaching staff couldn’t find a harmonious balance. — Ryan A., Lincolnwood
