During the Sixers' blowout loss in front of a national audience on Thursday, plenty of fans are calling for head coach Brett Brown's job. This isn't the first time that Brown has been criticized and it certainly won't be the last. He has been the subject of blame in the teams' close losses, the lack of development with Jahlil Okafor's defensive game while also consistently putting guys like Robert Covington on the floor as a starter despite him shooting 26 percent from the floor and 24.7 percent from beyond the arc. There are plenty of reasons to point the finger at Brown, but in all seriousness, the roster that he has to deal with is below mediocre and a coaching change probably wouldn't make that different.
More than 60 players have passed through Philadelphia during Brown's tenure and now with the team finally getting some good pieces for the future in Joel Embiid and Ben Simmons, the head coach's days could be numbered. In three plus seasons with the Sixers, Brown is 49-209, but as many know, the record reflects the situation that the whole organization has been enduring over the past few years.
Firing the head coach and inserting a "new voice" could be beneficial while it could also be a step back in this long process of rebuilding. Brown has played an integral part in this entire phase of "The Process", acting as the face of the team in front of the Colangelo's and the departed Sam Hinkie. Brett kept in touch with Dario Saric regularly when he was in Turkey, he played a big part in Joel Embiid's recovery and helped him after his brother passed away. Brown is also forced to put up with back of the bench NBA talent on the floor with the overturning roster. It's been a long road for Brown, but he's taken it in stride and stuck to the long-term outlook.
If the Sixers brass decided to part ways with Brown, they won't be able to do an all out coaching search, leaving four likely candidates to serve in the interim, one being former Sixers head coach Jim O'Brien.
Lloyd Pierce - Pierce joined the Sixers this season after spending the last two years in Memphis with the Grizzlies as an Assistant Coach in Player Development. Overall, he has 17 years of professional and collegiate experience. He began his NBA coaching career with the Cavs in 2007, where he served as the teams' player development coordinator for three seasons. During 2010-11, before joining the Grizzlies, Pierce was an assistant with the Golden State Warriors. He played four seasons overseas prior to returning to Santa Clara University to work as an Assistant Coach under Dick Davey from 2002-2007. Pierce was teammates with Steve Nash in college, leading Santa Clara to consecutive tournament seasons before graduating.
Jim O'Brien - Currently serving as the Sixers lead assistant, O'Brien posted a 303-327 record in nine seasons as a head coach in the NBA, enduring the most success with Paul Pierce and the Celtics from 2000-04, where he went a combined 139-119. During his stint with Boston, he led them to playoff appearances in 2002 and 2003, including the C's first trip to the Eastern Conference Finals since the 1987-88 season. He resigned in January 2004 and became the head coach of the Sixers, posting a 43-39 record in his lone season with Philadelphia, 10 wins more than the previous season en route to a playoff berth. Maurice Cheeks took O'Brien's place on the Sixers bench the next season. O'Brien was the last Sixers coach to post a winning record with the team.
Billy Lange - Lange serves as a player development coach on Brett Brown's staff after two seasons working under Jay Wright as an assistant coach at Villanova. It was Lange's second stint with Nova, having served as their director of basketball operations from 2001-04. He returned to Villanova after seven seasons as the head coach for the United States Naval Academy. In addition to his experiences at Navy and Villanova, Lange was also an assistant on Herb Magee’s staff at Philadelphia University and spent the 1998-99 season as an assistant coach at La Salle.
Eugene Burroughs - After spending two seasons as the shooting coach for the Sixers, Burroughs was named the head coach of the Delaware 87ers this offseason, his 21st season coaching overall. Prior to joining the Sixers, Burroughs was an Associate Head Coach at Penn State University from 2011-13 and working on the Marist College staff for the 2013-14 season. Burroughs served as Associate Head Coach at Penn State University from 2011-2013 before joining the coaching staff at Marist College for the 2013-14 campaign. Burroughs has also held coaching positions at Navy, Hofstra and American University. He is a native of Philadelphia and attended college at the University of Richmond, where he earned All Defensive honors during his junior year.
