NEW YORK — Point guard Jose Calderon signed Saturday with Atlanta, offering the Warriors some payroll relief in the process. After deciding to use its final roster spot this week on Matt Barnes in the wake of Kevin Durant's left knee injury, Golden State made good on its previous verbal agreement with Calderon. The Spanish national team member was signed and waived within two hours Wednesday so he could receive the roughly $415,000 he would have earned had he stayed for the remainder of the season. Joe just goes, 'The guy took a $400,000 pay cut to leave the Lakers. The Warriors waived Calderon, 35, so quickly to ensure he would retain playoff eligibility with whatever club he landed with next.
