The young Bulls were excited about their upset win over the Celtics in Game One on Saturday, but they approached their Sunday practice with determination and focus.

"Everybody was happy yesterday, but today we came into practice and everybody was focused," forward Tyrus Thomas said. "We understand we won one game, but in order to continue our season we have to win three more.

"We're happy with the win. We're not content. We're not satisfied. And we know what direction we need to head in."

Chicago knows that Boston is going to come out with a vengeance on Monday night, looking to even up the series before it heads to the Windy City.

"They're going to come out hungry, and to prove a point," Thomas said. "We're going to have to stay strong."
