ESPN's John Hollinger points out that the timing for the Bulls to make a coaching change seems to be perfect, with a combination of a season-long block of six home games, and some days off in between for the new coach to implement any changes during practice. And when you add in the fact that they have a guy with 14 years of head coaching experience currently serving as an assistant who could step in for Del Negro in Bernie Bickerstaff, the question likely becomes not "if," but "when" the change [from Vinny Del Negro] will be made.
