As the losses keep piling up for the young Minnesota Timberwolves and the scrutiny increases on interim coach Sam Mitchell, franchise star Kevin Garnett is throwing his support behind his longtime friend. Garnett approached reporters at shootaround before the Timberwolves played the Lakers in Los Angeles on Tuesday night and offered his endorsement of Mitchell as the right coach to lead the building process around 20-year-olds Karl-Anthony Towns, Andrew Wiggins and Zach LaVine. ''I feel real good about the progression of this team since Day 1 and I think it needs to be said and needs to be understood that I'm endorsing Sam Mitchell and our coaching staff and this organization,'' Garnett said.
