There’s definitely a trend here.
It’s not as if Georgia ran out of quality running backs after Chubb and Michel. The running game is slowly losing its outsized degree of emphasis (and note that accelerated under Coley).
Where do you think that percentage lands in 2021? (For comparison’s sake, note that last season Alabama ran on 52.8% of its plays, but its rushing yards were only 33.8% of its total yardage.)
