DALLAS -- After another blowout loss, Mavericks coach Rick Carlisle said he is prepared to use drastic measures to force improvement on what he feels is an underachieving team.

"The last week, I've had to literally scream in the face of two guys in practices and shootarounds to get the point across and I will do that," Carlisle said after Sunday's 111-86 loss to the San Antonio Spurs. "And I will continue to do that. If I have to start suspending guys for not doing things they're supposed to be doing on the court, I'll do it. And Mark [Cuban] and I will get into it about that. But somehow, things have got to change and it can't just be about that it's a tough schedule. It just can't."

For Carlisle, the Mavericks are a perplexing team. Even though they have nine new players on the roster, Carlisle said the Mavs' talent is good enough to compete with the better teams in the league.

"I've said it repeatedly that I like the roster," said Carlisle, who rejected all excuses after the team's sixth consecutive loss. "We're over 30 games into the season. We're not that new. We got to fix it."
