The Cleveland Plain Dealer (Brian Windhorst) reports:  The Cavaliers aren’t off to a great start at 1-2 heading into tonight’s game against the Mavericks, but the sky certainly isn’t falling. Yet Mo Williams, touted far and wide as the injection the Cavs needed, seems to be taking the offense’s somewhat shaky start hard. It has only been three games, two of them on the road at juggernauts Boston and New Orleans, and Williams hasn’t played all that poorly, averaging 13.3 points and 4.3 assists. But his body language and comments hint he seems to be putting quite a bit of pressure on himself to perform, an affirmation of his competitive nature. “Personally, I’m just not there yet. I’m still trying to get comfortable,” Williams said. “I’m trying not to lose any sleep over it. Tomorrow is a new day.”
