•  Axcess — founded by former United Football League Commissioner Michael Huyghue — paid for some vacation getaways for some of the team’s top players. The NCAA asked Allen about at least two trips that Allen claims he, Huyghue and UM quarterback Kyle Wright took to the Bahamas and, on another occasion, to Detroit for a Snoop Dogg concert in 2005 when Wright was a sophomore.

•  Allen corroborated Shapiro’s claims that the booster supplied dozens of UM players and potential recruits with cash, gifts, strip club visits, booze, parties and prostitutes. In a deposition last December, Allen detailed his own role in taking three high school recruits sought by UM — Ray-Ray Armstrong, Dyron Dye and Andre Debose — to a Miami strip club and giving them Shapiro’s money to have a good time in late 2008.

•  Certain Hurricane football and athletic department employees seemed to be aware of Allen’s and Shapiro’s wrongdoing three years ago, Allen testified in the deposition taken in Shapiro’s bankruptcy case. Allen said that UM’s football equipment manager Bobby Revilla asked him to write a letter to Shapiro in September 2009 to smooth out their differences for fear of Shapiro’s retribution against the university.

•  Shapiro had a serious gambling problem, betting millions of dollars on college and pro football games. He paid substantial fees to a high-profile South Florida sports handicapper, Adam Meyer, for his advice on game picks. Last year, Meyer agreed to return $900,000 in payments from Shapiro to a bankruptcy court trustee seeking to repay Shapiro’s investment victims, according to public records.

UM officials have maintained that they were unaware of Shapiro’s misconduct until NCAA authorities called the Coral Gables campus on a Friday in mid-August 2011. Tony Hernandez, senior associate athletic director, called Allen that day to say: “The NCAA’s coming in. … They want to speak to you.”

That was just days before Yahoo! Sports broke Shapiro’s vendetta-driven account, in which the rogue UM booster claimed that he “provided thousands of impermissible benefits to at least 72 athletes from 2002 through 2010” — shaking up the football powerhouse with a reputation for swagger.

Among those named as receiving benefits were two future NFL Pro Bowlers: Vince Wilfork, a defensive tackle who allegedly received $50,000 and two Cadillac Escalades from Shapiro, whose sports agency represented Wilfork when he was drafted in the first round by the New England Patriots in 2004. And Jon Beason, a linebacker picked by the Carolina Panthers in the first round in 2007, who allegedly received benefits from Shapiro while being represented by his agency.

“The [NCAA] knows everything,” said Allen, who was questioned on three occasions for a total of 13 hours by the NCAA authorities, including in February and July of this year.

“I don’t think they can prove everything. But they know everything.”

The Miami Herald has spent hours interviewing Allen — and others — and obtained a copy of his nearly 180-page deposition in bankruptcy court to help unravel the tale of what went wrong, how Allen and Shapiro were able to operate in plain sight and how the university failed to exercise proper institutional control.
