Like his coach, Horford is not sure how to predict how much energy his team will play with on a given night, but the Hawks center had a partial theory on why Atlanta was pumped up more on Saturday: The Hawks had lost two straight and three of four.
"What I've learned with this team is that until we're on the floor and we get going, we really won't know how we're feeling," Horford said after making 9 of 12 shots. "It's just a matter of us coming out with that energy, and I think our backs were against the wall. We needed to come out strong."
Williams started at shooting guard, but began the second quarter playing point guard in place of starter Jeff Teague, and scored 11 points in the period. The Hawks outscored the Bulls 25-6 over the final 6:58 of the half.
The third quarter was more of the same as Atlanta built a 72-47 lead.
Bulls coach Tom Thibodeux sat his starters in the final period.
"We got beat in every facet," he said after Chicago's two game winning streak was snapped. "Our defense wasn't any good, our rebounding was poor, and you're on the road. You've got to play 48 minutes. You look at Atlanta, they played (Friday), too. They were on the road. It's a will game."
