Sood testified on Monday that Richardson, who made around $250,000 per year as an assistant coach, was using his personal money to pay recruits.
"Let me be very, very clear: I have never discussed with Christian Dawkins paying Deandre Ayton to attend the University of Arizona", Miller said on March 1, 2018.
Last week, federal prosecutors played a surveillance recording of a meeting on June 6, 2017, in which Dawkins talks about Ayton and says Miller told him, "I'm taking care of everything myself".
But on Thursday, prosecutors played a surveillance recording from March 2016, when Dawkins traveled from Atlanta to Columbia, South Carolina, with alleged co-conspirator Munish Sood and Blazer to meet with then-Gamecocks assistant Lamont Evans about future National Basketball Association player PJ Dozier.
Dawkins has argued that it wouldn't make sense to bribe coaches because they don't have enough influence over players' business decisions.
Miller, who led the men's hoops program at Xavier University for five seasons before becoming head coach at Arizona in 2009, has denied violating any NCAA rules. Prosecutors said Richardson accepted $20,000 from agents in exchange for convincing players he coached to hire those agents to represent them.
Richardson: "You know what he bought per month?"
"But that's his fault", Richardson said. "He told me he's getting killed".
"You already know, Sean's taking care of Rawle and them", Dawkins said.
Cooperating witness Munish Sood testified on Monday that a meeting with Alkins' cousin, a man by the name of Rodney Labossiere, was arranged in Tucson on August 30, 2017.
Prosecutor Robert Boone confronted Dawkins with statements - captured on recordings from a 2017 Federal Bureau of Investigation sting featuring agents posing as investors in his management business - in which he brags about being tight with several coaches.
Cooperating witness Marty Blazer testified in this case that he believed Miller was involved in paying players, though Blazer provided no actual evidence through his testimony.
At one point, Boone asked Dawkins if he'd paid moms, dads, brothers and second cousins while recruiting high school and college players as clients. "I never have and I never will". "I have never arranged or directed payment or any improper benefits to a recruit or prospect or their family or representative, and I never will".
