Darren Collison led the Mavericks' second unit with 12 points, four rebounds, five assists and two steals in 32 minutes on Saturday. Derek Fisher and Collison played together at times, and Rick Carlisle continues to vary his lineups and rotations on a nightly basis -- he's even spoken of Vince Carter getting minutes as an obstensible PF. Collison is explosive enough to hold some value as a reserve, so try to remain patient as he settles into the role.
