The point you’re missing is MSU is 100% not a lateral job. A simple comparison of football budget and last 50 years football history clearly indicates that. Duke is historically a 3-9, 4-8 team year in and year out. Leaving for MSU also doesnt mean he cant take a bigger/better job in 1-2 years if that is his aspiration.
Will he do it or will he even be offered? Who knows, but your logic is flawed and you’re pretty much the only one who doesnt understand that.
The logic isn't flawed, I'm just not using your made up "measurement" looking at budgets of 50 years. In blue blood prestige, MSU eats behing OSU, Michigan, PSU, Nebraska, USC, Oregon, and maybe even UCLA in the big 10. That's about where Duke sits in ACC.
Averaging last 2 recruiting classes in conference, MSU recruits 10th, Duke 8th.
It's about as lateral as it gets and would be a waste of years of his life, and his name could very well never be hotter than it is now.
And even if your selected parameters mattered, a simple google search shows Duke has ~$20 million more in annual athletic revenue than MSU ($108 M vs $89M)
