During this decade long dry spell in men's sports, we've had coaches who sound the part behind a mic but don't deliver consistently to any extent on the field. (one exception: FF year)

Anticipate he'll be given one more year due to the 2021 extension. Otherwise, we would probably move on at the end of this year.
