LOS ANGELES — When it’s all said and done, the Lakers’ domination of the Nuggets will probably be much ado about nothing. But Saturday night, it was really something. Leading from start to finish and playing with a fire the Nuggets lacked, Los Angeles, with its season on the brink, rolled to a 119-108 Game 4 victory at rocking Crypto.com Arena. The Nuggets lead the first-round series 3-1 as they head back for Monday night’s Game 5 at Ball Arena, knowing that no NBA team has ever rebounded from a 3-0 deficit to win a seven-game playoff series.
