Spurs' Keldon Johnson energized after weight loss

San Antonio Spurs forward Keldon Johnson is preparing for another season in a changing role, with competition on the roster likely to keep him coming off the bench. After slimming down in the offseason, Johnson says he feels faster while retaining his strength and believes he plays better at a lower weight; coach Mitch Johnson expects the change may help him be more explosive and stay on the court longer. Johnson scored 15 points with five rebounds and two assists in 20 minutes in the Spurs’ preseason-ending win over Sacramento, reinforcing expectations that he will provide a scoring punch for the second unit.
