Billy Donovan Finally Explained His Bulls Exit

Billy Donovan's unexpected transition from head coach of the Chicago Bulls to a lead assistant role with the Spurs highlights the influences that shaped his career path and future ambitions in basketball.

Billy Donovan didn’t leave the Bulls with a mystery hanging over it. He says the move came down to timing, trust, and a simple belief that Chicago’s next front office should be able to pick its own coach.

Donovan, now working as a lead assistant on Mitch Johnson’s staff with the San Antonio Spurs, said he had fully expected to be away from the game for a while after stepping down on April 21, 2026. Instead, the Spurs reached out during the playoffs, and the conversation quickly pulled him back in.

“I didn’t really know what was going to happen. I loved my time in Chicago.

I loved the ownership group. They were very kind, offered me the opportunity to stay on as coach, and even offered me the opportunity to move into the front office.”

He said the Bulls’ front office changes made the decision feel clear.

“But they had to bring in a new front office. And I just felt that with a new front office coming in, that person should have the freedom to choose their own coach and build out the organization how they see fit, which was fine,” Billy Donovan explained.

Donovan added that he had originally planned to step away for a year and spend time in Gainesville with his children. Then San Antonio called.

“And I really went in with the impression I was just going to be out for a year. Come over here to Gainesville to see my kids and spend the year doing that. And then San Antonio had called during the playoffs, and they thought they may lose some staff members.”

That led to a conversation with Johnson, whom Donovan said he respects.

“And I didn’t know what to really think of it, but after talking to Mitch Johnson, the head coach who I got a lot of respect for, I’m just hoping that in some way I can bring some value,” he further added.

Donovan said the new role has also given him a different perspective on his place in the room.

“The one thing I am starting to realize more and more, every time I go somewhere, I’m now the oldest guy, and that was never really the case. But that’s happening, and I’m hopeful that I’m helpful in some way.”

He also made clear that the Spurs’ season and their approach mattered to him.

“I love the game, and they’ve obviously had an unbelievable season. I think Mitch and his staff have done a great job, and I love being a part of the competition,” Billy Donovan said.

Donovan closed by framing the move as a chance to return the favor to coaches who helped him along the way.

“I’ve been a head coach since I was 28, and I’ve been fortunate to have so many coaches help and mentor me along the way, so maybe this is just a way of giving back. What the future holds I can’t tell you, but the people in San Antonio have been gracious and accommodating about it, so I’m very excited about it, and hopefully I can bring some value and help.” Donovan concluded.

The Bulls announced his departure in April after what Donovan described as “thoughtful and extensive discussions” with ownership. In that statement, he said he was stepping away so the team’s search process could move forward and so the new leader could build the staff.

During six seasons in Chicago, Donovan went 226-256, a .469 winning percentage. His coaching résumé stretches back to 1994 and includes a 19-year run with the Florida Gators, and now he’s landed in San Antonio in a support role behind a staff he says has done a great job.

This isn’t the first time the Spurs have been linked to him, either. According to Spurs reporter Dusty Garza, San Antonio once viewed Donovan as a possible replacement when Gregg Popovich was weighing a move to the front office and retirement.

Now, years later, Donovan is back on an NBA bench, saying the job is less about a headline role and more about contributing wherever he can.

Billy Donovan Just Raised A New Concern Around Bulls Prospects

The college-to-pro path keeps getting messier, and Billy Donovan thinks the line should be a lot clearer. The former Bulls coach, now an assistant in San Antonio, said he has seen college coaches reach out to players in the G League about returning to campus basketball, even as those players have already made the jump into the professional ranks. His view is simple enough: once a player leaves college for a pro league, he ought to stay there.

Donovan did draw a distinction for undrafted players who are trying to find their way back into school ball, saying he is supportive of that route. What makes the issue feel more immediate for Chicago is the way Donovan framed the broader recruiting reality around the Bulls G League sphere, where teams are now navigating a market that did not exist in anything like this form a few years ago. The names he had in mind were not identified, but the concern he raised is one plenty of front offices are now watching closely. [Read more 🡒]

Bulls Linked To Intriguing Role In Proposed Lakers Mavs Trade

The Lakers miss on Jonathan Kuminga has already sent the rumor mill into a new gear, and one proposed response would drag the Bulls into the picture as a facilitator. NBA insider Jake Weinbach floated a three-team framework that would send P.J. Washington from Dallas to Los Angeles, while Chicago would be the third club helping make the math work in a deal centered on roster reshuffling and future flexibility.

For the Bulls, the appeal in a setup like that is less about headline talent and more about being the team that can smooth out the transaction for everyone else. The idea is still entirely speculative, but Chicagos role would be part of the same familiar trade landscape that often emerges when one team wants to simplify its books and another needs a clean path to the player it wants.

Caleb Wilson Is Giving Bulls Fans A Reason To Dream Early

Caleb Wilson did not wait long to make himself noticed in a Bulls uniform. The rookies Summer League debut turned heads with a 35-point burst, and that showing has only added to the buzz building around a player who already had team sources talking about his early impact. For a Chicago team in the middle of significant offseason change, any sign of upside matters, and Wilson has quickly become one of the more intriguing names in the mix.

What makes the early optimism more interesting is how much work sits behind it. Wilson battled injuries during his college season, then spent the offseason rebuilding his shot with relentless repetition, putting in marathon days from deep to sharpen the part of his game the Bulls believe can translate. The questions now are less about whether he can capture attention and more about how quickly that promise can become something useful once the games start to count. [Read more 🡒]
