This is where I think our perceptions differ. I remember CKW being on some hot lists (from national pundits), but it was generally accepted from anyone with any sense of the program, from the average IU fan to the insider, that the people making those lists were unfamiliar with the 7 year contract and the commitment to a longer opportunity than had previously been the norm at IU (and at other places). I think most people familiar with IU football knew that a 7 year contract pretty much guaranteed Wilson at least 5 years. My sense was always that those pundits were weighing Wilson's success against the typical three year opportunity, but the commitment to a long term rebuilding opportunity was explicitly stated when Wilson came.
I'll agree that getting a DC to a losing program, and to IU, and to IU with a new-ish coach that had shown improvement but had not yet met measurable goals, certainly presented challenges. I just think the mess at Purdue is on an entirely different level right now.
