Roethlisberger is spot on with his comments about the team-first attitude versus me-first. That OL group was tight they had when they were winning. The defense was a family. Watch guys like Ryan Clark, Ike Taylor, James Farrior talk about the defense. Heck, Troy Polamalu's entire Hall of Fame speech was about this.
After they all left the team stopped performing and you have guys like AB and Bell. Heyward often referenced guys not doing their job at the tail end of LeBeau's tenure here. Are you kidding me? Even now, who are the leaders on this team? No one on the offensive line. They didn't even help up their QB after allowing him to get beat up next year. Chase Claypool? lol. The offense is literally leaning on second-year Najee Harris to be the leader. Defensively you have Heyward and probably Watt and Fitzpatrick to some extent, but then there are guys like Bush who doesn't seem to live in reality with his play and Terrell Edmunds, who celebrated an INT with a bunch of backups last year when the team was down 20 points.
Yeah, maybe Ben doesn't need to say that now that he's retired, but he is spot on. When this team has a tight locker room again they'll be a Super Bowl contender.
