Riley has been through a transition year before. Although he was younger then. He took over an 8-5 Dennis Erickson team at OSU and matched that 8-5 his first year. Then, 7-5 the next year. And then 5-6 the following year.
Then he won 10 the next year!
Woot!
Every coach you think we should have hired has a "transition" year, sometimes in the middle of his stint, and sometimes it's a multi-season trough.
If you want the only coach to post seven consecutive 9 win seasons, he's at Youngstown State because no major program wanted him.
None of this is as obvious as you try to make it.
