A day after being arrested for allegedly trying to extort Nike for more than $20 million, lawyer Michael Avenatti began following through on a threat to expose the shoe and apparel giant for paying high school basketball stars.

On his Twitter account Tuesday morning, Avenatti wrote, "Ask Deandre Ayton and Nike about the cash payments to his mother and others. Nike’s attempt at diversion and cover-up will fail miserably once prosecutors realize they have been played by Nike and their lawyers at [the law firm Boies, Schiller & Flexner]. This reaches the highest levels of Nike." Ayton played collegiately for one year at Arizona before becoming the first pick in the NBA draft last year. Avenatti included no specifics to back up his allegation.

Ayton was the No. 1 recruit in the Class of 2017 after playing summer basketball under the Nike umbrella. After an intense recruitment, the 7-footer signed and played one season with Nike-sponsored University of Arizona. He was later the No. 1 pick in the 2018 draft and is currently a rookie for the Phoenix Suns. Upon turning pro, Ayton eschewed Nike and signed a four-year endorsement deal with Puma.

Avenatti also claimed Oregon freshman center Bol Bol, a top-five NBA prospect and the son of former NBA player Manute Bol, “received large sums of money from Nike,” and the attorney even attempted to implicate Nike director of elite youth basketball Carlton DeBose.

Bol Bol and his handlers also received large sums from Nike. The receipts are clear as day. A lot of people at Nike will have to account for their criminal conduct, starting with Carlton DeBose & moving higher up. The diversion charade they orchestrated against me will be exposed — Michael Avenatti (@MichaelAvenatti) March 26, 2019

Bol suffered a left foot injury in January that ended his season and career at Oregon.

When contacted for a comment, Oregon released the following statement through a spokesperson: “We are unaware of any evidence that would support these allegations. Diligent inquiry last summer into the amateur status of our student-athletes revealed no indication of improper payments made to any student-athletes or their families.”

And of course, Avenatti didn’t stop there. He brought up Adidas consultant Merl Code, who received a six-month prison sentence for his role in college basketball’s federal fraud scandal.

The corruption at Nike was rampant with Merl Code and increased with his apprentice DeBose after Code left for Adiddas. Those above DeBose knew all about the payments. Nike conspired to route many of the payments through a convicted felon. Nike then lied to the government. — Michael Avenatti (@MichaelAvenatti) March 26, 2019

Code's counsel declined to comment about Avenatti’s allegations.

Avenatti also tweeted that Nike has not been sufficiently cooperative with the ongoing federal investigation of basketball: "Contrary to Nike’s claims yesterday, they have NOT been cooperating with investigators for over a year. Unless you count lying in response to subpoenas and withholding documents as “cooperating.” They are trying to divert attention from their own crimes."

If Nike was cooperating with the government for over a year relating to this scandal (they weren’t - this is a lie), where are the disclosures in their SEC filings? There are none. Wait until the SEC begins their investigation & starts asking why Nike hid this info from investors — Michael Avenatti (@MichaelAvenatti) March 26, 2019
