5. WR Antoine Green
A big play touchdown in the preseason finale seemed to vault Green into the final wide receiver spot on the Lions' 53-man roster entering the season. Then he did not play a single snap against the Chiefs, on offense or special teams.
Green (19.1 yards per catch over his last two seasons at North Carolina), offers a speed and downfield threat the Lions could use. Marvin Jones had a dismal outing against the Chiefs. While Josh Reynolds has a nice connection with Jared Goff, how much he'll bring on a week-to-week basis is a question mark.
This isn't a call for Green to play 50 snaps. But he should get on the field some moving forward, at least while Jameson Williams serves his suspension. The seventh-round rookie literally can't play less than he did in the season opener.
4. S Tracy Walker
This is a hard one. Walker has made a nice recovery from a torn Achilles in Week 3 last season. By all accounts he had no setbacks, and is 100 percent healthy now. But with Kerby Joseph in place, and C.J. Gardner-Johnson shifting to playing safety with rookie Brian Branch taking the nickel corner role, there's just not a lot of room for the Lions' leading tackler in 2021 to play.
Walker played nine special teams snaps and zero defensive snaps against the Chiefs. That could be an attempt to ease him back in coming off a major injury, which is understandable. It's also understandable that there just aren't enough safety snaps to go around when everyone's healthy. Having Walker as depth is certainly a nice place for the Lions to be.
That said, zero defensive snaps should not become the weekly norm for Walker. Like Green, he can literally only play more from here.
