I'm not sure about CTA getting 2 more years.
I think he's gone if we only win 4. If we win 5, it depends on how we play. If no significant change in the staff and the product on the field, and a butt kicking by Purdue, I think he's gone. If we look more focused and competitive, he'll get 2020 and perhaps a small extension. If we win 6, he probably gets extended. After the last 2 years, the difference between 5 & 6 is huge. Also, to win 6 we'd have to win 2/4 of at MD, at Neb, at Purdue, or NW at home. That will be hard to do and worthy of notice if it happens.
