Golden State sank an NBA Finals record nine 3-pointers in the first quarter, four of them by Thompson, who scored 16 points in the opening period.
Trailing by six (113-107) after JR Smith drained a 3-pointer with 3:09 remaining, the Warriors finished the game on an 11-0 run, with Durant accounting for 7 points and Curry the other 4. Love was fouled on the pass, but the attempt actually somehow went in for LeBron, giving him two points and Love a free throw attempt for his troubles.
The NBA's best-of-seven championship was billed as the ultimate grudge match between the league's last two champions, and some pundits felt it could go down as one of the most hotly-contested series of all-time.
They surpassed the 13-win streaks of the 1980s Los Angeles Lakers and the 2016-17 Cleveland Cavaliers to set the record, although "Showtime" Lakers star Magic Johnson claimed Monday his squad would have swept the Warriors in a series.
But Golden State with Durant is on another level than the teams Cleveland roughed up in the Eastern Conference, and the Cavs just couldn't hold them down long enough.
Warriors coach Steve Kerr said that Durant has played with objective throughout the series.
"He took over", Kerr marveled.
"When you watch it, it doesn't necessarily seem as bad because you understand that the things that you can't control", he said. "But we gave a great effort, and the result just didn't turn out the way we wanted to". "Basketball is a insane game".
"I don't like the position, but in the same sense I do", he said. LeBron had another strong start, then Irving worked his wizardry. James and Irving combined for 77 points, and both shot over 50 percent from the floor. They also played 46 and 44 minutes, respectively, and missed their last five shots during the final five minutes.
Kerr was convinced that they'd eventually wear down. But Curry hit back-to-back 3s on a 10-0 run to close the entertaining and exhausting quarter.
"I mean, it's hard to envision", Irving said.
They will certainly need to get more out of their role players as well.
The first two in this series were delightful in their own right because there were brilliant performances and the pace was out of this world but they were basically routs and we lost our attention and edge in the final few minutes. "That's just my personal opinion".
Even in Game 2, the Cavaliers looked improved and came away with a 19-point loss. This was Durant tested as he has never been before, and delivering.
"I'll probably be replaying that play for a while", Irving said afterwards, shivering not from the way the game ended but his post-game dip in the ice bath. "Doing what he's supposed to be doing".
Klay Thompson said there were no special plays for Durant or spoken instructions, just a consensus determination to "Get that man the rock".
