The losses have usually piled up by the game. Kobe Bryant also has spent nearly every waking hour receiving treatment on his 37-year-old body. But even with the Lakers (8-30) entering Sunday’s game against the Utah Jazz (15-20) on Sunday at Staples Center on pace for their worst record in franchise history, Bryant has mostly kept a positive attitude in his 20th and final NBA season. “I just hide it a lot better now,” said Bryant, who is listed as probable to play on Sunday because of his sore right shoulder. “When you have championship talent, it (ticks) you off a lot more when you’re not playing up to that level of potential.” The current Lakers do not have that potential. But they have won three of the past six games, the latter two losses still competitive within the final moments.
