In 1987, the first year college basketball had a three point line, Butler’s Darrin Fitzgerald hit 5.6 per game a figure that has never been reached again in the NCAA or NBA, and more than any NBA TEAM averaged that year. He never got a chance in the league, and that’s where his career ended
He hit them at 43.6% accuracy.
Fitzgerald played Butler’s 28 games that year, peaking at 12 threes made in a game, and averaging 26.2 points. https://www.sports-reference.com/cbb/players/darrin-fitzgerald-1.html
This was a very different Butler team than in the early 2010s where they were making runs to the championship game - that year they finished 12-16, and they had only made one NCAA tournament to that point, in 1962.
That, combined with NBA teams completely failing to see any value in the shot for close to another decade, him being undersized (5’9) and not a prototypical PG (averaging less than 4 assists) allowed him to go under the radar and never get a chance with an NBA team. This is despite Fitzgerald still maybe having the best three point shooting season still ever in college ball.

Every NBA team averaged less than three three pointers made that season.
For those curious, the NBA record is 5.3 made per game from Curry in 2021. Nobody else in college basketball has ever made 5 per game. His record for total three pointers made stayed until Curry in 2008.
