Bill O’Brien is kind of a coaching enigma. Most fans know him as the guy who traded DeAndre Hopkins for a bag of chips or the dude who had to follow Joe Paterno at Penn State, but his resume is actually a wild, 30-year odyssey across every level of the sport. It's not just a list of jobs. It’s a series of high-stakes "fix-it" projects that either ended in Coach of the Year trophies or explosive sideline shouting matches.
Honestly, if you look at bill o'brien past teams coached, you see a pattern. He’s the guy you hire when things are broken, or when you need someone who speaks "Belichick" fluently. But he’s also a lightning rod.
From the Ivy League to the ACC Grind
Before he was "Teapot Bill" on the sidelines of an NFL stadium, O’Brien was just a guy grinding in the 90s. He started at his alma mater, Brown University, in 1993. He coached tight ends first, then moved to inside linebackers. You don't see many offensive "gurus" spend time coaching linebackers anymore, but that’s where he cut his teeth.
Then came the Georgia Tech years. This was a long stint—1995 to 2002. He stayed there for eight seasons, moving from a graduate assistant to the offensive coordinator. This is where he actually met George O’Leary, a guy who would influence his hard-nosed style. He even followed O’Leary to Notre Dame for about five minutes before a resume scandal blew that up, sending O’Brien to Maryland (2003-2004) to coach running backs.
He then landed at Duke. Yeah, Duke football in the mid-2000s. It wasn't pretty. They went 0-12 in 2006. But strangely, it was that struggle that helped him land on the radar of a certain hoodie-wearing coach in Foxboro.
The New England Patriots: The First Stint
In 2007, the New England Patriots hired him as an offensive assistant. He walked into the building during the 16-0 season. Talk about timing.
By 2009, he was the quarterbacks coach for Tom Brady. Think about that pressure. You’re coaching the greatest to ever do it. In 2011, he was promoted to Offensive Coordinator. That’s the year he and Brady had that famous "screaming match" on the sidelines against the Redskins. Most people would be terrified to yell at Brady. O’Brien didn't care. That fire is exactly why he got his first head coaching shot.
Saving Penn State (2012–2013)
When people talk about bill o'brien past teams coached, this is usually the chapter they respect the most. He took the Penn State job in 2012 when the program was basically in radioactive fallout. The Sandusky scandal had just happened. The NCAA had dropped the "death penalty" lite on them. Scholarships were gone. A bowl ban was in place.
Everyone expected Penn State to fall into the basement of the Big Ten.

Instead, O’Brien went 8-4. He won the Bear Bryant Award. He kept the roster from dissolving. He convinced guys like Christian Hackenberg to stay. It was arguably the best coaching job of the decade because he wasn't just calling plays—he was holding an entire university together. But the NFL came calling quickly.
The Houston Texans: Power and Its Pitfalls
O’Brien went to the Houston Texans in 2014 and, for a while, he was actually really good at it. He won 9 games in his first year with a rotation of mediocre quarterbacks. He won the AFC South four times.
But then, things got... complicated.
O’Brien wanted more control. By 2020, he was the Head Coach and the General Manager. That’s a lot of hats for one person. He made the infamous trade of DeAndre Hopkins to the Arizona Cardinals for David Johnson and a second-round pick. Fans in Houston still haven't forgiven him for that. When the team started 0-4 in 2020, the front office had seen enough. He was out.
The "Saban Rehab" and the Return to the Roots
After Houston, he did what every fired coach does: he went to the "Nick Saban School for Coaches Who Want to Coach Good Again" at Alabama.
He spent 2021 and 2022 as the OC for the Crimson Tide. He coached Bryce Young during his Heisman season. While Alabama fans were sometimes frustrated with his red-zone play-calling, the numbers were objectively huge.
Then, the Patriots called again. He went back to New England in 2023 to try and save Mac Jones. It didn't work. The offense was stagnant, Belichick’s era was ending, and the whole thing felt like a "too little, too late" reunion.
Where is Bill O’Brien Now?
As of 2024, he’s back in his home state as the head coach of Boston College. It’s a full-circle moment. He’s back in the ACC, back in New England, and back in the role of the "rebuilder."

Looking at bill o'brien past teams coached, the takeaway is simple: he’s a floor-raiser. He takes bad situations and makes them competitive. He takes decent situations and wins division titles. The friction usually starts when he tries to become the architect of the entire building rather than just the guy on the sideline.
If you're following his current tenure at Boston College, watch how he handles the roster. His history at Penn State suggests he’s elite at managing a program under pressure. His history in Houston suggests he’s at his best when he has a clear separation between coaching and front-office duties. For fans looking for a "stable" hand, his career is a masterclass in navigating the highest highs and lowest lows of football.

To get a better sense of his impact, look at the "coaching tree" he’s helped cultivate, including names like Mike Vrabel. It’s a career built on intensity and an almost obsessive focus on "The Process"—a trait he clearly picked up from his time with Belichick and Saban.
For anyone tracking his progress at BC, keep an eye on his recruitment of local Northeast talent. That was his bread and butter at Penn State, and it will likely be the key to whether his current stint becomes another trophy-laden chapter or another sudden exit.
