The Lakers have issues in the wake of their two-game losing streak, and Pau Gasol’s heavy workload is the biggest of them. He played 45 minutes, 30 seconds two nights after going 44:54 during the Lakers’ loss to the Utah Jazz. He scored 13 points, grabbed 12 rebounds and added three assists and three blocks tonight. But he looked fatigued at times and was frustrated by the Pacers’ tight defensive coverage on him. Things aren’t likely to get better for him when the Lakers face his younger brother, Marc, and the Memphis Grizzlies on Tuesday. Lakers coach Phil Jackson made it clear tonight the team will not sign a free agent to serve as backup until Andrew Bynum is ready to play next month. Theo Ratliff could be out up to six weeks after he had knee surgery. Gasol has no backup and his team-leading average of 39:04 is not going to go down any time soon.
