HOUSTON -

If the Warriors looked just a tad bleary-eyed at Saturday morning’s shootaround, it was likely becaue they were up too late, watching Game 3 of the other series.

Portland and Denver played the first postseason quadruple overtime game since 1953 on Friday night. The game lasted three-and-a-half hours and ended in the wee hours of the morning, Houston time. Portland prevailed at home, 140-137.

“I wanted to go to sleep but I couldn’t, just like everybody else,” Steve Kerr said.

Andre Iguodala, who knows how important sleep is, was also watching.

“That’s exciting basketball, two teams fighting it out,” Iguodala said.

The box score was crazy, with Portland’s CJ McCollum playing 60 minutes and scoring a game-high 41 points. Damian Lilliard posted 58 minutes of play and Denver’s Jamal Murray logged 55 minutes.

“That was usually my total for a postseason,” Kerr cracked.

Rodney Hood - who played against the Warriors last postseason as a member of the Cavaliers and was traded to Portland in February - was the overtime star, with seven points in the final overtime period. Seth Curry scored Portland’s final two points - both free throws.

The teams turn around to play Game 4 on Sunday. No one on the Warriors expects there to be much of a toll on the players from the extended game.

“In my younger days, it probably wouldn’t be a problem,” Iguodalas said, adding, “mentally, that’s fatiguing.”

Youth will be on their side.

“They’re young, they’ll get over it quickly,” Kerr said.

But will the rest of us recover from staying up to watch it?
