Los Angeles Lakers (27)
Big flaw: The young and struggling defense
Playing NBA-caliber defense is hard, especially for young players. Put one or two gifted young athletes in a strong defensive unit and it's certainly possible for them to thrive, but when the system is almost entirely made up of them there are going to be speed bumps. Luke Walton's Lakers are no exception as they rank 29th in the NBA in defensive efficiency, allowing 109.8 points per 100 possessions.
They've particularly struggled when at least three pieces of their young core share the floor. Of the 10 three-man combinations featuring three of Jordan Clarkson, D'Angelo Russell, Julius Randle, Brandon Ingram and Larry Nance Jr., the only two with a better defensive rating than the team's 109.8 are Ingram-Nance-Clarkson and Ingram-Nance-Randle. In the 84 minutes that the cornerstone trio of Russell, Ingram and Randle have shared the floor, they've allowed more than 116 points per 100 possessions.
Solution: Just keep playing the kids
The only way to get better is to play. Since the Lakers have made it clear it's all about the future, the best move here is no big move.
Though no Laker is averaging more than 30 MPG, Walton is playing the young guns at critical moments. Randle, Clarkson, Ingram and Russell rank among the top five this season for the Lakers in clutch time played (final five minutes and the score within five points) along with super sub Lou Williams. While that has certainly played a part in the Lakers having the NBA's fourth-worst defense in those situations, it's part of a necessary learning curve.
Each of the young Lakers are making individual strides on the defensive end of the floor, according to ESPN's real plus-minus (RPM). A year after ranking outside the top 60 among point guards in defensive RPM, Russell is now inside the top 40. Randle has improved his DRPM from negative-1.55 to plus-0.27 and Nance now ranks among the top 20 power forwards, 10 spots ahead of noted defensive presence Serge Ibaka, among others.
Even Clarkson, whose DRPM of minus-2.14 rates below the likes of Kyrie Irving and Austin Rivers, has improved by that metric for the third straight season. Though Ingram ranks 79th out of 80 qualified small forwards, that was to be expected this early. The best thing the Lakers can do for all five is just keeping giving them opportunities -- and, hey, maybe it'll help them keep their pick.
