In a wide-ranging interview with carltonfc.com.au Ratten conceded there had been some tough lessons learned from the alcohol-fuelled end of season break-up that ultimately saw Eddie Betts, Andrew Walker and Ryan Houlihan banished from the club for one month.
Ratten said everyone involved with the club, particularly the players, had worked hard ever since to ensure those lessons didn't go unheeded.
"Have we just brushed it under the carpet? No. I think we've put things in place from a club point of view and, I suppose, a football point of view so that we can help support each other," Ratten said.
"I think they're some of the lessons that we've learned along the way and we've become better for it.
"Sometimes things do happen in football that are out of your control. We spoke about that and asked 'were we in control of that situation?' Yes we were, but we let it get out of control.
"Now the players understand fully their responsibility and the responsibility of how they can support each other which is a big key to it."
Skipper Chris Judd was roundly criticised for his involvement in the incident, but Ratten said those views were unfair.
"I think the expectation on Chris is extremely high. He is a leader of the club and holds a lot of responsibility, but I think there is a leadership group that's there with him," he said.
"All of the players as individuals have now got to stand up and be accountable for their actions.
"To pass the blame onto him is, I think, very unfair."
Leadership consultants Leading Teams have worked extensively with the Blues since last October and Ratten believes he is already seeing some of the benefits of the programs put in place.
Part of that process will see the Blues take the unusual step of not publicly naming the leadership group around Judd in 2010.
"It is [a bit out of the ordinary] but it's something we discussed," Ratten said of the initiative.
"Does anyone need to know? It's our business and people lead on the field so hopefully everyone will be able to work out through their actions who's leading the team on the field and around the club.
"It's our leadership group and no one else's, but if it gets out, it gets out."
