I provided a list of examples of position coaches getting promotions to coordinator positions. Some of those were internal promotions. One of those examples was VA TECH - who took a LB Coach from Florida State and made him their DC. Happy to do some more research, as the ones I mentioned were just from the last coach hiring cycle. Do I need to make this in all caps or maybe change the font color to help you understand?
There is a narrative going on that we are too big time to promote a position coach to DC. This is silly as it happens every year at P5 universities. In fact, our first year entering Big12 sounds like a great time to take a risk as we wont have heavy expectations.
Again - you brought up Tuiaki's resume. What is in his resume that is in the realm of Nua's?
