This is not hard news -- yet. What it is a rumor with a lot of smoke. The rumor in question is Ken O'Keefe leaving Iowa to become the Quarterbacks Coach for the Miami Dolphins (and new head coach Joe Philbin, who worked with O'Keefe on the Iowa staff for several years early in Ferentz's tenure).
EDIT: And confirmation from the Des Moines Register, too. It's really happening, people.
We'll have much more on this as soon as we get more information.
