(CBS) In the aftermath of Bulls power forward Carlos Boozer on Monday morning expressing displeasure over his lack of playing time from coach Tom Thibodeau in the fourth quarter of games, general manager Gar Forman said he was “disappointed” that Boozer chose to make his frustrations public.

“I’m disappointed that Carlos didn’t keep that in house,” Forman said according to CSNChicago.com. “I think we’ve seen Tom does a terrific job managing guys’ roles, managing their minutes. In that situation, Taj (Gibson) has played very, very well.”

Gibson often plays down the stretch, as Thibodeau prefers his defense. At the time of his comments yesterday, Boozer hadn’t played in the fourth quarter of the previous two games.
