They use Brilen Allen as the short yardage back and the passing down back. I would think Bree probably is going to be in close to like a 50/50 snap share split with Brilen, though he'll have the backfield touches about 65% to 35%.

STACKED’s take

NeutralRole

Short yardage and passing down specialist in 50/50 snap split.

Used by the Bills as the short yardage back and passing down back, limiting Breece Hall's role; expected to operate in close to a 50/50 snap share with Hall, though Hall will receive about 65% to 35% of backfield touches.
