I understand the reflex after someone dies to ‘not speak ill of the dead’, but IMO that doesn’t mean we should distort history.
After trying Hall of Fame former players as head coaches for 13 years the Infante hiring in 1988 represented a signal change in direction for the Packers organization. It could be said that he was the first "real pro football coach" the club hired since Lombardi and, especially after that 1989 season, his common ethnic ancestry with Lombardi and that both came to Green Bay after outstanding offensive coordinator careers in the NFL seemed to be "de javu."
Phil Bengtson and then Dan Devine were hired after Lombardi and although both failed, each was a “real pro football coach”. While Forrest Gregg was a Packers legend he had also been an NFL HC for 7 years, (barely) had a winning record and led the Bengals to the Super Bowl in 1981. That qualifies as a “real pro football coach” too, doesn’t it?
And anyone feeling “déjà vu” comparing Infante to Lombardi wasn’t paying any attention whatever or never saw the Lombardi Packers. The Packers won 4 games in 1989 by one point. They were tied for 8th in the league in scoring offense and 18th in scoring defense (Infante whose expertise was offense never saw his Packers team rise above 22nd in scoring except for the 1989 season). Infante finished with a 24-40 record in Green Bay and then went 12-20 in Indianapolis. In six seasons as an NFL HC, he recorded one playoff appearance - a loss. As I mentioned, the record shows he was best suited for an OC job in the NFL.
IMO the "signal change" in the direction of the organization occurred when Harlan created the VP/GM job and hired Wolf to fill it. Wolf observed the team for about the last month of the 1991 season. He said he witnessed a "country club" atmosphere in spite of the team finishing that season 4-12. Could anyone imagine such a thing being said about any Lombardi team?
