On a night when his fellow reserves combined for five points and six turnovers and lost Draymond Green to a sprained ankle after only 4 1/2 minutes, Warriors guard Jarrett Jack refused to be part of the team's weak link. He broke out of an uncharacteristic individual slump to lead the Warriors to a 105-97 victory over Detroit on a Wednesday night when the starters couldn't find much help aside from their reserve guard. "It wasn't our best game, not the prettiest, but I think we showed what we're capable of during stretches," Jack said. "We know that we're a very capable offensive ball club, but on some nights, that's not going to be the thing that can carry you. The one thing you can always provide is effort." Jack provided his usual infectious dose of effort and picked up his production with 19 points on 7-of-11 shooting and five assists to zero turnovers in helping the Warriors put it back into coast mode after Detroit trimmed the deficit to 90-86 with 6:05 remaining. He hit a step-back jumper, helped to force a shot-clock violation at the other end, knocked down a pair of free throws and then contested Kyle Singler's missed three-point try as the Warriors extended their lead to 10 points and moved to 4-2 on their season-long, seven-game homestand.
