The 76-year-old Mills says that while the verdict was inevitable, SBF refused to adopt a key strategy in the face of his co-founders throwing him under the bus on the witness stand, Bloomberg reports.

"I thought it was almost impossible to win a case when three or four founders are all saying you did it," said Mills. "Even if they're all lying through their teeth, it's really, really hard to win a case like that."
