Last season for the San Francisco 49ers, the running back unit was effectively a two-headed monster in Carlos Hyde and undrafted free-agent Matt Breida, with Raheem Mostert as the backup back (he was rarely used).
2017 fourth-round rookie Joe Williams never got to contribute despite being the target of a trade by the 49ers, going on injured reserve due to an ankle injury.
Fast forward to this season, and it’s pretty much the same running back squadron for the 49ers, but with one important difference.
Hyde is gone and is now a Cleveland Brown.
