Spack can get a much better opportunity than Purdue and no way he would come back with Morgan here. In fact Morgan is no secret and no good coach would come here with M organ as their AD.
I think had Morgan not exercised his ego (I think he is afraid Spack would give him a 'swirly' so the lack of hiring him was to get back at all the bullies from his days in HS) and hired Brock Spack we would have seen 7 years of 7-5 football. Maybe the occasional 8-4. On a "down year" 6-6.
