Yes Payne is gone, but his original scholarship would have been up in 2013, just like Hubbard's was slated to be open in 2014. You are right in the totals that are open, but I don't think it is wise to just go out and sign a bunch of guys to sign a bunch of guys. Unless some players fall into Iowa's lap say at the JUCO level and then sign a couple guys that can redshirt, then you fill as many possible.
In looking at how the staff has handled filling the open scholarships and not expecting Payne or Hubbard leaving. There is a major rebuild at work and just filling scholarships is not what they have done so far and I don't expect that to happen now. So again, fill 4 this year and three the following year and have no unexpected departures, the roster will be balanced in its classes and won't be carrying over scholarships.
