Prince appears to have the special teams phase solved (off the top of my head it's won us 3 games in the past 2 year - Ill St., OSU, UT). Since 2003, the underlying problem is defense. I completely agree the defense has, in the 4th quarter, been a let down in both of our losses. But that doesn't mean that the offense still doesn't have problems. The OL is terrible. And if the OL isn't terrible, then our OC is terrible, and if our OC isn't terrible then our QB is terrible.
Against BCS teams, the offense has put up 13 against Auburn, 21 against UT, and 24 against ku. The offense isn't exactly a juggernaut. The offense is not complicated, dynamic, or hard to figure out. It's based on (flawless) execution and it has a very difficult time overcoming negative plays because we tend to want to chip away at the field instead of get yardage in chucks (aside from the occassional trick play or Jordy Nelson fade). Which is the part I don't understand because Freeman was put on the field because he could "reach areas of the field that other QB's couldn't". The offense could do more and it's not, just like the defense.
