I was looking up Colorado's good early-90s teams and the 2001 squad that curb-stomped Nebraska in the XII CG, which took me to 2001 Oregon. I had filed them under "the Joey Harrington team", but those Ducks had 2 different 1,000-yard rushers. Their defense also gave up almost 300 yds per game through the air. Hmph.
Another, separate, observation I've had in doing all this research: an incredible percentage of very good teams (10-2 or better) have had dreadful field goal kickers. It seems like as many have FG% success rates in the 50% range as have better than that, which is astounding to me. And some of the punt return averages are abysmal as well - even from some notable 'name' athletes.
