No one knows or could know, bit Painter didn’t hold Purdue hostage. They actively chose to respond to Mizzou’s offer, which is common in coaching circles and business in general. I know two people involved in the group(s) internally that responded to his offer (one a long time faculty member who, like me, is an IU alum. Anyone close to your athletic department would know who this person is. The other is a trustee who continues in that position today). MP is very likely perceived as essentially “tenured” at Purdue, given his longevity as both a coach and former player. It very likely means most schools wouldn’t consider him for a coaching opening because he’d never leave WL.
Always funny to read the comments of people who, first and foremost, immediately demonstrate they have no earthly idea what happened specifically or how things like this work. Humorous and mind boggling, all at once.
