All these guys [ex. Herbstreit, RSmith, Pollock, Fauria, May, even Bayliss et al] have watched years of football. They all are seeing the same thing. This team has proved that it can do stunningly positive things in the areas [general offensive and defensive plays, yardage production, line-of-scrimmage power, etc] which translate into wins against almost anybody on the field. The areas of error are SO spectacular that no one can believe them. AND because all the areas, though usually "peripheral" to the core of team function, are both the clear and only reason for defeat, AND are usually fixable by teams, no one can believe that they will continue to go on.
Listen to all these guys talk. They're shaking their heads unanimously in disbelief. They now see, paradoxically, after two losses, the on-field proof of how dangerous this team is. They see this team as an angry monster waiting impatiently to get all its "parts" smoothed out. I'll bet very few teams in the country would REALLY like to play ND right now. Who wants to be the one on the other side of the line when the turnovers and penalties stop??
