If Football Study Hall (Bill Connelly = GOAT) is correct, returning production at WR has the biggest impact. That would bode very well for us.
Edit: went to find the FSH link for the original article and found a better one - updated version from 2019. Tennessee is #2 in returning production. And I now see the defensive side to this - returning DB tackles matters most on D.
2019 CFB returning production, ranked a better way
Fwiw Minnesota is the next highest P5 team at 10th. We outrank other P5 programs by a good margin. Hmm reason for optimism? Or do we believe more in our trench deficiencies? Truth may be in the middle.
