Curry connected on his 270th three-pointer of the season midway through the second quarter to give Golden State a 37-27 lead. Allen set the record in the 2005-06 season for Seattle.
Curry’s record-breaker came just over a quarter after he tied the mark in the first quarter and on his seventh three-point attempt of the game.
Allen took the record from Dennis Scott, whose record, 267, stood for ten years before Allen broke it. In setting the new mark, Allen shot 41.2 percent on 653 attempts.
Eight years later, Curry broke it with a more efficient stroke. He went into Wednesday’s game having knocked down 45.5 percent of his 589 three-point attempts before needing six attempts against the Trail Blazers.
When the NBA adopted the three-point shot in the 1979-80 season, Brian Taylor led the league with 90 threes — a record that stood for four seasons before Darrell Griffith broke it by one in 1983-84, then upped his own mark to 92 the following season.
It wasn’t until Danny Ainge finished with 148 threes in 1987-88 that a player hit more than 100 in a season. John Starks was the first to crack 200 when he hit 217 threes for the Knicks in 1994-95 before Scott set his mark the following year. Nine players have owned the record.
