I think unless an injury happens, he's just going to be stuck as this wide receiver three. So, I think he's more just an injury dependent stash.

Injury-dependent stash; target share threatened by Okonkwo's return

While Williams showed high efficiency with four targets on 12 routes, the source views him as an injury-dependent stash rather than a viable Week 2 starter, as he is currently the team's fourth wide receiver in snaps. He saw targets in the middle of the field, but his future target share may be threatened if Chigoziem Okonkwo returns to the lineup, as they operate in similar areas of the field.
