Glenn Rivers, known to the basketball world as "Doc," already has a legacy in Milwaukee basketball, and he's one of the top-10 all-time winningest coaches in NBA history. Reports have indicated he's a frontrunner to take the reins in Milwaukee, where the Bucks have just fired first-year coach Adrian Griffin.

Here's what to know about the man strongly connected to the sudden head-coach opening with the Milwaukee Bucks:

Where has Doc Rivers coached previously?

Rivers is ninth on the NBA's all-time coaching wins list with 1,096 victories, and he's two shy of Larry Brown for eighth place. Overall, he owns a record of 1,860 wins and 1,097 losses, good for a .590 winning percentage.

Rivers won an NBA championship as head coach of the Boston Celtics in 2007-08, then led the Celtics back to the NBA finals in 2009-10. It's one of four places where he's been head coach, with 24 years of head-coaching experience.

His most recent stop was Philadelphia, where he was coach from 2020 to 2023. He was fired after the 76ers lost in the conference semifinals to Boston in May.

Rivers became head coach of the Orlando Magic in 1999, three years after his NBA playing career concluded, and he won NBA Coach of the Year in his rookie season (and never won the award again). He was with the Magic for five seasons before getting fired early in the 2003-2004 season. He worked as a commentator for ESPN and NBC but was then hired by Boston in 2004, where he spent nine seasons.

He was actually traded by Boston to the Clippers after the 2012-13 season for a first-round draft pick, and he immediately became vice president of basketball operations in Los Angeles. He spent the next seven years with the Clippers, starting with a franchise-record 57-win season.

Rivers stepped down following the 2020 "bubble" season when the Clippers were beaten by Denver in the conference semifinals. He was hired by Philadelphia mere days later.

Doc Rivers was a Marquette University standout

Rivers, who became a McDonald's All-American at Proviso East High School in Illinois, played at Marquette University from 1980 to 1983.

He was named a 1982 Converse All-American and scored 1,234 career points with the program. He still sits third in the Marquette record book for points as a freshman (434 in 1980-81) and scoring average (14.0 points per game), plus second in field goals made (182).

His bank shot at the buzzer during that freshman season helped MU stun Notre Dame, then ranked No. 5 in the country.

In 2012, he was named the school's Alumnus of the Year. He's one of nine basketball players whose jersey has been retired by the university.

He was a second-round pick by the Atlanta Hawks in the 1983 NBA Draft. He played 13 seasons in the NBA with Atlanta, San Antonio, the Knicks and Clippers, making the all-star team with the Hawks in 1988. For his NBA career, he averaged 10.9 points and 5.7 assists per game.

What awards has Doc Rivers won in his NBA coaching career?

Rivers was named NBA Coach of the Year one time, in 1999-2000 after his first season with the Magic. Still, he made a list of the 15 greatest coaches in NBA history released by the league in 2021-22, part of the NBA's release of the 75 greatest players in league history.

He took second in the Coach of the Year voting in 2007-08 with Boston and 2018-19 with the Clippers.

Playoff struggles have been the biggest mark against Doc Rivers

In the playoffs, Rivers is just 111-104 (.516) with only one title and two NBA Finals appearances in his near-quarter-century of coaching.

Nonetheless, he's made the playoffs 19 times and missed just five times, and one of those seasons was his rookie year as a coach, when he led Orlando to a .500 record and earned Coach of the Year.

Neither the Clippers nor the 76ers made it to the conference finals under Rivers, and the Magic never won a playoff series under Rivers in four attempts. One of those losses came in 2001, when the Milwaukee Bucks beat Orlando in the first round of the playoffs, 3-1, in Rivers' first postseason coaching experience.

In addition to the two trips to the NBA Finals, Boston made a third Eastern Conference Finals under Rivers.

Where did Glenn Rivers get the nickname 'Doc?'

His nickname has roots in Milwaukee; he famously came to Marquette's campus as an eighth-grader for a summer basketball camp wearing a T-shirt riffing on the "Dr. J" nickname of NBA star Julius Erving. Marquette assistant coach Rick Majerus is credited with giving him the name "Doc," and it stuck.

"I talked to him when he was an eighth-grader at one of our camps," Majerus said after the program won a significant recruiting battle for Rivers. "Glenn was wearing a T-shirt that said "Dr. G" on it. So I went up to him and asked him, 'Hey, Doc, you any good?' and he said, 'I'm OK.' And he showed me by tomahawk-dunking the basketball with as much grace and style as I've ever seen for a kid his age."
