The Lakers lost 114-108 to the Phoenix Suns last night to leave them with back-to-back defeats, giving them a 10-11 record so far this season.
The shooting guard, who was playing his second game since returning from an Achilles injury, told reporters: "It's a process. You just continue to figure out what you can and can't do. Every game, you try to step up and do a little bit more and just go from there.
"It's there. We've just got to execute a little better. The willingness and competitiveness is there. We just have to make sure we come out in the right areas and execute it."
The Lakers face the Oklahoma City Thunder on Friday.
