I wonder the reason behind this. Makes no sense to me as a coach can easily change their mind after a year or in Bill's case get one next year as his sabbatical is not by choice. 3 is the shortest I would have it.
I don't like the change. I think they should have kept the five year rule. It's clear after that whether they're done or not. It also makes it look like they changed it just for him.
That said, I don't think there's any chance he's not a first-round hall of famer, Borges or not.
