This was going to happen eventually and I agree that with all that talent they will be back with a vengeance.
The days of Wisconsin loading up with 6-7 sub 9:10 2 mile recruits and dominating the Big 10 every year are over. American high school talent has evolved. Every school in the Big 10 has better prepared recruits. Illinois, Michigan, and Indiana in the 1980's would have had to give a 9:00 Midwest guy a full ride to keep them from going to Wisconsin on partials or even books.
They are a young team. They will be back.
