OKLAHOMA CITY — It got so bad for the Lakers tonight in Game 4 that Kobe Bryant left the bench and returned to the locker room for a massage long before the final buzzer. Insert your own joke here. He finished with 12 points on 5-for-10 shooting in 32 minutes, 4 seconds and raised a whole new round of postgame questions about his health. The Lakers have two days to regroup and regain their lost momentum before playing Game 5 at Staples Center. The series is tied at two wins apiece. What’s next is anyone’s guess.
