Duncan Robinson was rewarded for one of the most unlikely journeys in the NBA.

Robinson signed a five-year, $90 million contract in the opening hours of free agency to remain with the Miami Heat.

According to ESPN's Adrian Wojnarowski, it's the largest contract ever for an undrafted player.

Robinson's journey to this point is one of the most unique in the NBA. He began his college career at Williams College, a Division III school in Massachusetts. According to Yahoo's Jeff Eisenberg, Robinson didn't have any Division I offers after high school.

However, after averaging 17 points and 6 rebounds per game as a freshman, Division I schools began to call Robinson's old prep school coach and admit they regretted not recruiting Robinson, according to Eisenberg.

After a successful freshman season, Robinson got a flood of offers from Division I schools. Robinson decided to explore his options, as his head coach at Williams was also leaving for a new job. Robinson ultimately landed at the University of Michigan.

While Robinson was an effective role player at Michigan, finishing fourth in school history in made threes, he still didn't get drafted to the NBA. Robinson ended up playing for the Heat's Summer League team in 2018, then signed a two-way contract, bouncing back and forth between the G League and NBA.

Robinson didn't become a full-time NBA player until the 2019-20 season, where he surprised teams with his lights-out shooting from downtown. In 2019-20, Robinson averaged 13.5 points per game on a blistering 66.7% effective field goal percentage, thanks to 46% shooting from three and 92% shooting from the foul line.

Over the last two seasons, Robinson is third in the NBA in total made threes, with 520. He's one of two players to make over 300 combined threes and shoot better than 40% - the Brooklyn Nets' Joe Harris is the other.

Harris is a good comparison for Robinson. Harris was a second-round pick and bounced around the NBA, even getting waived by the Orlando Magic, before landing with the Nets. After emerging as a deadly three-point shooter, Harris signed a four-year, $72 million contract last offseason.

Reports before free agency had pegged Robinson getting $15-18 million annually - and he got $18 million.

Weeks before free agency, Robinson told JJ Redick on the "Old Man and the Three" podcast that at times he stressed about how free agency might unfold before having a reality check.

"When I think about this [contract] number vs. this number and think, 'Oh, I want more than that,' it's like, oh my goodness," Robinson said. "If the me of four or five years ago when I'm like, in my dorm at Williams College, eating late-night peanut butter-and-jellies heard myself complaining about this bulls---, I would slap myself in the face."
