Pete Carroll has again hit out at the NCAA's handling of its investigation into the USC program.
Carroll recently led his team to Superbowl glory, blowing away the Denver Broncos to help the franchise win their first ever championship.
Despite that the 62-year-old is still bitter about the NCAA's investigation into allegations of rule violations during his time as head coach of the USC Trojans.
Probes by both USC and the NCAA found that former USC star Reggie Bush had forfeited his amateur status by accepting gifts from agents which is against college football rules.
Members of other sport teams from USC, including their basketball team, also fell foul of the rules.
The NCAA doled one of the harshest punishments in its history - chalking off the final two wins of the Trojans' 2004 national championship season, as well as all of its wins in 2005 alongside other sanctions.
Bush also handed back the Heisman Trophy he had won in 2005.
Carroll has re-opened the debate on the issue by claiming that the NCAA's investigation was 'done with too much emotion'.
'It was dealt with poorly and very irrationally and done with way too much emotion instead of facts," he said at a speaking engagement at a school according to the Los Angeles Times.
He added that during his time dealing with the NCAA, he felt like they never appreciated what the Trojans' program was about.
"I listened to the venom that they had for our program" he explained.
"They didn't understand a thing about what we were all about. .. They never were here. And they didn't want to hear it. They never even got close to hearing what we're all about."
However he did concede that mistakes had been made at USC.
"We just didn't know what was going on," he said. "Had we known, I would like to think we would do the right thing and would have stopped everything and fixed it by doing what we should have done. But, unfortunately, because we didn't know, the university gets killed over the deal."
