The struggling Dallas Mavericks' backcourt is in flux and they have added a veteran with a championship pedigree to try to help stabilize it.

Derek Fisher is expected to make his debut with the club Saturday night when the Mavericks host the Detroit Pistons trying to avoid their first four-game skid.

Fisher took part in his first practice with Dallas (7-9) on Friday after signing earlier in the week. The 38-year-old has not played since Game 5 of the NBA finals for Oklahoma City.

MEMPHIS – The Pistons have their first winning streak of the season. A modest two-gamer, but a winning streak nonetheless. Pushing it any farther won’t be easy, given that the next step comes on the road against arguably the NBA’s best team of the season’s first month, but Corey Maggette wanted to make sure the Pistons maximized their odds.

One change, one dramatic new look. With only one alteration to the starting lineup incurred, the Pistons appear to have found the right balance between first and second units, between scoring and defending – and between winning more and losing less.

Greater change comes below the surface. The only constant to the second unit from the start of November to its end: rookie Andre Drummond.
