There definitely seems to be an advantage to being a first offer. But if you are only the first offer because you offer everyone under the sun, does it really count as a first offer? Can recruits recognize that? Should Iowa use that as negative-recruiting against other schools (notably Neb, ISU, Minn)?
It is an interesting dilemma. Would you rather see Iowa go the Nebraska route, or maintain their current practice of deliberate evaluation prior to an offer?
