Swanigan originally committed to Michigan State University, but later decommitted and committed to Purdue University. He was named Big Ten Freshman of the Week three times, a record at Purdue. He was also named to the Big Ten All-Freshman Team and also received a National Freshman of the Week award. Swanigan finished the season with 10.2 points per game and 8.3 rebounds per game.
Swanigan grew up in an unstable home due to his father, Carl Swanigan Sr., who had a crack cocaine addiction. Swanigan's mother, Tanya, had six children. Swanigan moved between Utah and Indianapolis during his youth, spending time in homeless shelters.[3]
Swanigan inherited two key features from his biological father—height and a tendency to obesity. The elder Swanigan, who died in 2014 from complications from diabetes, was 6 ft 8 in (2.03 m) and weighed nearly 500 pounds (230 kg) at his death. By the time Swanigan was entering eighth grade, he was 6 ft 2 in (1.88 m) and 360 pounds (160 kg).[3] His father had many brushes with the law, battled drug addiction for most of his adult life, and physically assaulted his wife. According to a story in Bleacher Report, Swanigan was accidentally dropped by his mother as an infant, leaving a bruise on his face; this incident led her to move with her children to Salt Lake City. For the next decade, the family bounced between Indianapolis and Utah; he recalled that he lived in five different homeless shelters and attended 13 different schools by the time he was 13.[3]
When his mother decided to move the family to Houston, his older brother Carl Jr., concerned that Caleb would keep gaining weight if he moved with his mother, called his former AAU basketball coach, Roosevelt Barnes, a former three-sport star at Purdue who played on the school's 1980 Final Fourteam and now a successful sports agent. Barnes, living in Fort Wayne, Indiana, agreed to take Caleb in if he could adopt him and raise him as his own son. Barnes adopted Swanigan prior to his 8th grade year. Barnes addressed Swanigan's eating habits and, after receiving clearance from a cardiologist, began putting him through workouts similar to those Barnes himself went through in college. By the time Swanigan finished high school, he had slimmed down to 260 pounds (120 kg).[3]
High school career
In the fall of 2011, Swanigan attended a basketball camp led by NBA former coach John Lucas after Roosevelt Barnes convinced Lucas to let him into the invite-only camp in Louisville.[4] When it came to selecting his high school, Swanigan's guardian Barnes said, "When he chose his high school, his high school had never really done much in the tournament, and his goal was to win a state championship at a school where that had never been done before."[5] Swanigan attended Homestead High School and wore the same number as Barnes, number 44.[4]
As a senior, he was named Indiana Mr. Basketball and led Homestead to a first-ever state title. He was ranked as a top-20 national prospect in his class.[6] He was named a McDonald's All-American.[7] Swanigan averaged 22.6 points and 13.7 rebounds as a senior.[8] Academically, Swanigan maintained a 3.1 GPA and graduated in three years instead of the usual four.[9]
Swanigan finished his career at Homestead with records for career points (1,649) and rebounds (1,048), as well as the single-season points (704) and rebounding records (424).[6] He was also second all time for career blocks (106) and assists (204).[10]
National team career
Swanigan qualified for the 2014 U17 World Championship Team, beating out twenty other players vying for a spot to make the 12-man squad.[11] Swanigan played in the U17 World Championship Game. The team finished with a 7–0 record and earned a gold medal in Dubai, United Arab Emirates, extending the USA's total record at the U17 World Championship Game to 23–0.[11] He finished the series with 8.0 points per game and 5.7 rebounds per game,[9] and was the most efficient player on the U17 team, with a 69.6 shooting percentage.[12]
Before starting his freshman season at Purdue, on June 18, 2015, Swanigan was announced as a member of the 12-man 2015 USA Basketball Men's U19 World Championship Team for the 2015 FIBA Under-19 World Championship that won a gold medal in Heraklion, Crete.[13] On making the team, Swanigan said, "I always set goals for myself. I set goals for this spring. One of my goals is to make this team to end my high school career."[13] To prepare for the games, Swanigan played in the Nike Hoop Summit, the McDonald's All American Game, and the Jordan Brand Classic. Swanigan did not take part in the Indiana-Kentucky All Star Game so he could attend the U19 training camp.[14] He was one of five players returning from the gold medal-winning U17 squad. Swanigan's teammate Vince Edwards was also in the running to make the team, but was cut at the round of 16.[15] The team finished 7–0, and Swanigan averaged 6.1 points and 4.4 rebounds per game.[9]
College career
Recruiting
Swanigan had several teams recruit him and offer scholarships; Arizona, Kentucky, Cal, and Duke were among the schools that gave Swanigan an offer.[16] Caleb Swanigan verbally committed to Michigan State on April 10, 2015, but decommitted on May 7.[17][18] He said, "I just felt like it was better basketball-wise for me."[3] Similar to his high school decision, Roosevelt Barnes said, "He wants to win a national championship and said he wants to do it in the state of Indiana and wanted to do it at a place he's never done it before."[5] Some people believe Barnes had ulterior motives in adopting Swanigan, to which Barnes said, "Maybe if I wanted to develop the next hot dog-eating champion, the next Joey Chestnut, people would have a legitimate gripe." Swanigan had not consulted Barnes before he committed to Michigan State, and some believe that since Barnes played sports at Purdue he was a major influence in Swanigan decommitting from Michigan State. Barnes said that was not the reason Swanigan switched, and the primary reason for Swanigan choosing Purdue was the presence of two centers that were taller than 7 feet, Isaac Haas and A. J. Hammons, which allowed Swanigan to play the 4 spot.[4]
He decided to stay in-state and chose Purdue on May 19.[19] Swanigan announced his decision by tweeting "#BoilerUp". Swanigan was Purdue's first Indiana's Mr. Basketball recruit since Glenn Robinson in 1991, and was the first McDonald's All-American for Purdue since 1996.[5] Swanigan joined Ryan Cline and Grant Weatherford in Purdue's 2015 recruiting class.[6]
Swanigan chose to major in general education/educational studies.[10] Swanigan chose the number 50 to honor his father who had died at 50 years old.[4] Swanigan started every game his freshman year. His highest-scoring game was in a win against Wisconsin in Purdue's last regular-season game, where he scored 27 points and missed only one shot from the field. He scored six points and grabbed 10 rebounds in #4 Purdue's loss to #13 Arkansas–Little Rock in the 2016 NCAA Division I men's basketball tournament, and did not play at all during the overtime period.[20][21]
After his freshman season, Swanigan was one out of 162 underclassmen to enter their names for the 2016 NBA draft. However, despite being one of 63 invitees for the NBA Draft Combine that year, he ultimately decided to return to college on May 25, which was also the new date set for players to withdraw their names from the draft and try again for another year. An NBA scout said, "I think he has a chance if he can improve his jump shot and help defense. Big-time rebounder, works hard on his own. He's still more undersized center than power forward, though."[3]
Swanigan set several records as a freshman. He was ranked as a top-10 freshman nationally. He set Purdue program records for most rebounds by a freshman (282), games started (34), double-doubles (8), and rebounds per game (8.3).[10] He was also the first major-college player in 25 years that had 600 points, 400 rebounds, and 100 assists in a season.[22]
2016–17 season
Similar to his freshman year, Swanigan started every game as a sophomore. Swanigan set his personal record for points against Norfolk State with 32, while shooting 83% from the field. Swanigan also managed to grab 20 rebounds, making it one of his four games with at least 20 points and 20 rebounds that year.[23]
As of March 6, 2017, Swanigan was second in the nation in rebounds per game (12.6) and led the nation in double doubles (25) for the 2016–17 season. He was rated first in CBS National Player of the Year voting.[24] In his sophomore season, Swanigan broke several Purdue records, including rebounds in a season, double-doubles in a season, and an NCAA record with four 20–20 performances. Purdue finished as the regular season Big Ten Champions, but were knocked out in the quarterfinals of the Big Ten Tournament by Michigan, the eventual tournament champions.[25][26]
Purdue entered the 2017 NCAA men's basketball tournament as the 4th seed in the Midwest bracket and played Vermont in the first round. Purdue came away with an 80–70 win for their first tournament win in five years, with Swanigan posting a double-double with 16 points and 14 rebounds.[27][28] Purdue continued its tournament run against Iowa State in the second round. Swanigan flirted with a triple-double with 20 points, 12 rebounds, and 7 assists in Purdue's 80–76 win.[29] In the Sweet Sixteen, Purdue squared off against Kansas. Swanigan was 3-for-4 from the three-point line, finishing with 18 points and seven rebounds. Purdue ended their tournament run in a loss to the Jayhawks, 98–66.[30]
At the conclusion of the season, Swanigan announced he would declare for the NBA draft and not hire an agent, therefore maintaining his college eligibility for at least one more year, if necessary. Swanigan was expected to go in the late first or early second round of the NBA draft.[31] Swanigan finished his academic career with a 3.60 GPA during his last semester, and maintained a cumulative GPA of 3.34.[32]
As a sophomore, Swanigan continued to set records at Purdue.

Swanigan was one of 16 players honored by the Network for accomplishments between 2010 and 2019.[36]

I have been thinking of this moment for a long time. I know this is only the first step in my professional career, but I am extremely excited for to begin this journey." Boilermakers coach Matt Painter said, "We are thrilled that Biggie has achieved his lifelong dream of being selected in the NBA draft.
