Sorry but it is kind of lame to cherrypick our attrition and use that to suggest our talent is way less than Iowa's. I don't have the time or inclination to go and research all the attrition Iowa has also experienced (Don't know why you guys seem to think attrition of good players only happens at CU), but I did one Google search and the 1st link was interesting:

Iowa las 7 running backs to attrition in a period of 3 years and something like 4 in 1 yr. No idea about the rest of their losses.
Anyway, I am done with this stupid argument. Those of you want to carry on believing that our talent last year reflects our ranking and that Water Bottle & Co were not meaningful factors, go for it. I'll leave you 5 people to debate amongst yoursevles because
the rest of the college football world is pretty comfortable with the fact that Embree, EB, & Co. were way over their heads and were an embarrassment to the college coaching profession. (I am not talking about their ability to be position coaches but to be HCs and coordinators).
