No one has depth anymore, not like the pre-portal days. Oregon lost 30 players to the NIL chase. Texas Tech lost 31. Thirty-one players left Jedd (Dedd) Fisch at Washington, 31 bolted Michigan, 37 boomed out of Oklahoma; Purdue turned over 58.
A coach brings in new players to replace them-- the Ducks have signed 11 so far--but the fact remains the best players on the second unit move on to become starters elsewhere. Everywhere there are runs at certain positions: Lanning and his staff lost six defensive backs and seven defensive linemen. Turnover requires retraining.
