Correct me if I'm wrong but Betts and Kasper were Hayden Fry recruits that Kirk inherited. You should adjust your numbers accordingly.
19 for Hayden Fry
4 for Kirk Ferentz
True but that's now how it is recorded in the Iowa archives so I followed ******. You could also probably add another year on to the Ferentz era (17) with no additions likely to be added this coming NFL draft as well.
Pretty telling of position priorities and approach to the game in my opinion when you consider the length of time this covers.
