I think you misunderstood the part about under wing. TandT have invaluable resources, information , doner connections, knowledge of Iowa’s administration personalities, that facilitate a smooth coaching transition. It doesn’t have to be that way, but seems if possible, it would be good for all involved. Out going coaches, incoming coaches, administrators. And yes he does need to learn about Iowa, like any prospective coach coming in any job.
The only thing is if Donny and Brands can and are willing to.
Don’t think there is a negative side to it.
