Lets be honest...
the 2003 and 2004 offenses were not very good...they were incredibly one dimensional; they just so happened to be backed by dominant defenses and special teams play. The 2009 offense, as clutch as it was, was far worse than the defense...that is, the D still carried the team. 2002 is the only year that the offense carried the team. So even during the successful years, the offensive issues were masked by great defenses.
This isn't about 1 game. It's about 2.25 years ineptitude at offense after 13 years of...well, mediocrity being the norm. That's going to lead to a lot of pent up frustration.
Not many people are asking for Ferentz to leave...they do ask that he changes with the times.
