The Buss family is entering an agreement to sell majority ownership of the Los Angeles Lakers to Mark Walter, the CEO of TWG Global and owner of the Los Angeles Dodgers, sources familiar with the deal told NBCLA on Wednesday. The deal, first reported by ESPN, has a valuation of about $10 billion, a source told NBCLA.

The Lakers and Buss clan have been inextricable since 1979 — the longest active ownership tenure in the NBA — but Mark Walter's stunning coup effectively ends this improbable era.
