The Golden State Warriors are losers of five of their last seven games and are watching their defense abandon them since a 10-game winning streak that bridged December and January.

The Trail Blazers lead the NBA in scoring average and took down the Minnesota Timberwolves 115-104 on Saturday.Golden State limited opponents to 92.8 points during its winning streak but is surrendering 108.4 over the last seven contests, including a 121-120 home setback to the Minnesota Timberwolves on Friday. "We've done a bad job - everybody on the floor, breakdowns," coach Mark Jackson told reporters. "There is not one guy that is doing their job defensively. Everybody in uniform has been bad defensively for us and it's disappointing right now." Portland can spread teams out beyond the 3-point line or pound it inside to LaMarcus Aldridge.TV: 9 p.m. ET, CSN Northwest (Portland), CSN Bay Area (Golden State)ABOUT THE TRAIL BLAZERS (33-11): Portland took a 113-101 decision at Golden State on Nov. 23 in a game that included three ejections.
