Skinner played at the University of Massachusetts. While on the freshman team in the 1970–71 season, the varsity team was led by Julius Erving, in what would be Erving's final season in college. Skinner was also a teammate of Rick Pitino. Skinner scored 1,235 points in his three years on the varsity squad. He led the team in rebounding each of those three years, and in scoring in his junior and senior seasons. As a senior, he averaged a double-double with 18.8 points and 11.0 rebounds. That scoring average also led the Yankee Conference. He recorded the first triple-double in UMass history, with 28 points, 18 rebounds and 10 assists against St. Peter's on Dec. 28, 1973 in Springfield MA. Skinner was a three-time Yankee Conference First Team selection. He led UMass to two straight YC titles in the 1972–73 and 1973–74 seasons. As a senior in 1973–74, he was the team captain and an All-America honorable mention selection. His jersey number 30 was retired in a ceremony at UMass on Feb. 18, 2004.
Professional
Skinner was drafted by the Boston Celtics in the 1974 NBA draft. He never ended up playing with Boston. Instead, he joined the New York Nets in the ABA, where he reunited with Julius Erving. The pair helped the Nets win the ABA title in 1975–76. In his total ABA/NBA career, he spent time with the Nets, Pistons and 76ers. An odd footnote to Skinner's career is that he's the only player in NBA history to earn a DNP for both teams in the same game.
After retiring from his playing career, Skinner entered the college coaching ranks. He served as an assistant coach at Marist from 1982 to 1984, and then at the University of Rhode Island from 1984 to 1988. He was named head coach at URI beginning with the 1988–89 season, replacing Tom Penders. Skinner coached the Rams for nine seasons, during which he won the Atlantic 10Coach of the Year award for the 1991–92 season. He is also credited for recruiting many of the players of the Rams' 1997–98 team – Cuttino Mobley and Tyson Wheeler – which reached the Elite Eight of the 1998 NCAA Tournament. During Skinner's tenure, the Rams were selected to two NITs and two NCAA Tournaments. He was inducted into URI's Athletic Hall of Fame in 2000.
On April 17, 1997, Skinner was hired to lead Boston College after Jim O'Brien left for Ohio State. Nearly all of the Eagles' prominent players followed O'Brien to Ohio State, leaving Skinner with a depleted roster. As a result, the Eagles struggled for Skinner's first three seasons in Chestnut Hill, winning only 12 games in Big East play and 32 overall. After the Eagles struggled in Skinner's first three seasons in Chestnut Hill, he guided the 2000–01 team to the Big East regular season title with a 13–3 record—their first regular season title in 18 years. The Eagles went on to win the Big East Tournament, and earned a #3 seed in the NCAA Tournament. He was named the season's Coach of the Year both Nationally and in the Big East. In the 2004–05 season, the Eagles became the first Big East team in history to start a season 20–0. The Eagles were ranked #4 in the AP Poll at the time, and even reached as high as #3 later in the season. Though they won the conference regular season title, the Eagles fell in the Quarter-Finals of the Big East Tournament. As a #4 seed in the 2005 NCAA Tournament, they were upset by #12 seed Milwaukee. Skinner was named Big East Coach of the Year in 2004–05. The 2005–06 Eagles finished with a 28–8 record, which stands as the most wins in a single season in BC history. They also advanced to the Sweet 16, tying the second-deepest NCAA run for an Eagle team. During the season, Skinner also became the all-time winningest coach in BC history, surpassing O'Brien's 168 wins. Through the 2009–10 season, Skinner led Boston College to seven NCAA Tournaments, and one NIT. On March 30, 2010, Skinner was fired as head coach at Boston College following only his second losing season of the millennium. Almost a year to the day after his firing, Skinner took part in a phone interview with Boston Globe sportswriter Mark Blaudschun. Ending a year of self-imposed silence about what transpired at Boston College, Skinner defended his record, stating, "I ran a good program, I graduated my kids. Everybody has problems, but we addressed them and handled them in a matter that satisfied every one." Skinner continued the interview by noting that he felt had he been at BC during the 2010–11 season, the Eagles would have been more of a factor in the national picture. "I know the potential we had", he said. "We would have had a dog in this fight, and that we don’t bothers me." His remarks, and the fact that his interview ran on the front page of the Sports section of The Boston Globe, demonstrated the ongoing controversy regarding his firing in March 2010.
Bryant
In 2013, Skinner joined the staff of his former assistant coach, Tim O'Shea, as an assistant coach at Bryant University, and his first coaching job since being let go at Boston College.
Kennesaw State
On April 26, 2015, Skinner was named the sixth head coach in school history at Kennesaw State, replacing Jimmy Lallathin. On February 21, 2019, Skinner announced his resignation from Kennesaw State effective at the end of the season.
Head coaching record
Two teams, same game
During the 1978–79 season, Skinner was traded by the New Jersey Nets to the Philadelphia 76ers along with Eric Money for Harvey Catchings and Ralph Simpson. The trade occurred while a protest filed by the Nets against the referees of an earlier game against the 76ers, which New Jersey had actually won, where head coach Kevin Loughery was called for three technical fouls. The rules only allowed two to be called, and the league granted the Nets' appeal. Therefore, the game was considered suspended at the point of the illegal technical foul call and the game would be restarted and finished from there when the two teams met again, by which time the trade had occurred. The players involved in the trade were allowed to suit up for their new teams when the suspended game resumed, and everyone but Skinner, who had not dressed for the original game either, got to play.
