Darren Collison scored 15 points on 5-of-8 shooting (no threes) with four rebounds, six assists, and three steals in the Mavs' 117-114 overtime loss to the Thunder on Friday. Collison is going to be a low-end point guard option barring a major change to the Mavs' rotation. O.J. Mayo added 18 points on 6-of-16 shooting (including a clutch three late) with three rebounds, seven assists, and two steals, and Dirk Nowitzki went cold with 18 points on 5-of-19 shooting, nine rebounds and one steal in the loss.
