Yeah he's got a big house here. There was a great article last week though that reminded us that Brohm turned down playing QB for Notre Dame in college when UofL was playing on a damn baseball field. He turned down coaching with Nick Saban (twice) to stay at UofL. His family lives here and his brothers and father played here. It's pretty well beyond just "coming home" for him.
As far as Purdue goes they gave him a bunch of money and an opportunity when he was coaching at WKU. He took it and is doing good job. You love him, we love him. We get it. Financially the schools are comparable and it's clear yourr fan base is way more on edge than ours.
We can ask ourselves all day what motivates a coach to take a job but with the kind of history he has here at UofL it's hardly a lateral move in his eyes. Or so it looks from his past decisions. If the compensation is close we have the edge with facilities, history and path to playoffs.
The odds are in our favor he comes home (literally). Even if we don't you have to know he's not staying at Purdue more than another season. He'd stay to properly finish a rebuild and get a monster job offer from somewhere awesome.
Go cards, Beat Purdue.
