The Chicago Bulls suffered a difficult 91-81 loss to the Bobcats on Monday.
The Bulls were outscored 28-18 in the first quarter.
"Right now we are not a 48-minute team," Tom Thibodeau said. "I have to figure this out. I have to make us ready. We need an edge to start the game. We cannot ease our way into a game and say, 'OK, we're good, we'll get ourselves corrected.'
"It doesn't go like that."
