The Los Angeles Lakers have agreed to a four-year, $48 million contract extension with forward Jarred Vanderbilt, a person with knowledge of the deal told The Associated Press on Friday. The person spoke to the AP on condition of anonymity because the Lakers haven't announced the long-term deal with their defensive specialist. The Lakers acquired Vanderbilt from Utah in February, and he quickly became a key rotation player during their impressive late-season run to the Western Conference finals.
