The NBA regular season is here, and it started with a star-heavy doubleheader on Tuesday night.

The Thunder outlasted KD on ring night, while Luka and Steph battled in L.A. Here are the biggest takeaways from NBA opening night.

Jimmy Butler led the Golden State Warriors to a road win over the Los Angeles Lakers on opening night while the Oklahoma City Thunder outlasted the Houston Rockets on opening night.

That said, a 40-year-old LeBron James will miss the Lakers' opener against the Warriors. The four-time league MVP and four-time NBA champ is dealing with sciatica and is reportedly eying a mid-November return. James' early-season absence could set the stage for the beginning of a Dončić MVP campaign.

Shai Gilgeous-Alexander and the OKC Thunder will host Russell Westbrook and the Sacramento Kings at 7 p.m. Tuesday.
