Not worried at all. Sure, I wish they would go 4-0 and just wait for the next opponent, but that's not realistic in the Western Conference. Just look at the game. You could tell they played like it was a regular season game. UNFORCED turnovers. This wasn't magnificent defense or anything. Even Duncan was just kind of jogging to screens, no urgency. I give the Mavs credit, they took advantage of the TOs, but if they need over 20 of those to win, it's just not going to happen.
