After a four-point win vs the Brooklyn Nets, the Pistons blew a 13-point lead in the fourth quarter, then lost in overtime to the Portland Trail Blazers. They followed that with an upset victory over the Indiana Pacers.

Josh Smith scored 31 against the Trail Blazers before a 30-point effort versus a Pacers team that leads the NBA in field-goal percentage defense.

"We keep putting him on the block and he's being aggressive, attacking the rim," coach Maurice Cheeks told the Pistons' official website. "He's getting a ton of opportunities. He's just playing a full basketball game."

This could be the chance for Smith to break out as he is averaging a career-low 15 PPG.

"We're forming an identity ourselves," Smith said. "That has to be being a physical team, try to dominate the paint."

Even though the Celtics have the same record as the Pistons, coach Brad Stevens made Detroit sound like title contenders at Tuesday's practice, according to ESPN.com.

"I've always thought they were one of the most talented teams, especially in the East," Stevens said. "They've got a 3-man who is playing like an All-Star in Josh Smith, who is not a normal 3-man. You've got a guy like (Greg) Monroe who's a bonafide scorer, who can get the ball on either block and score, can drive it from the elbow and score, can make mid-range shots. (They have) probably other than Dwight Howard the next most athletic center in the league in Andre Drummond. And then you've got perimeter guys in (Rodney) Stuckey, (Brandon) Jennings, (Chauncey) Billups, on down the line, (Will) Bynum, (Kentavious) Caldwell-Pope is playing well, that can go off. So you've got a lot of guys that can do a lot of things. They're a very formidable group in my opinion."
