3. LB Jack Campbell
Campbell's Pro Football Focus grade (53.2) was the second-worst among Lions' defensive players against the Chiefs. But he made an impact play, showing great instincts and quick reaction to break up a pass a couple plays before Brian Branch's pick-six.
Alex Anzalone's every-down role isn't going away, for better or worse, and Derrick Barnes was the second-highest graded Lions' defender against Kansas City according to PFF. A 25-yard pass completion "credited" to him by Pro Football Reference (if not PFF) was a big demerit on Campbell's Week 1 performance. But his raw talent demands he will see the field more moving forward.
2. WR Kalif Raymond
Raymond had one catch for 20 yards against Kansas City, as he played just 19 offensive snaps. With how rough a game Marvin Jones had, as previously mentioned (two catches and a fumble on six targets; 35.1 Pro Football Focus grade), Raymond's role as the Lions' punt returner is not a reason for him to lack offensive snaps.
A shift in playing time may have started during the season opener. Jeff Risdon of Lions Wire noted Jones played 28 of his 39 snaps before Raymond played an offensive snap.
Mike Payton of AtoZ Sports has expressed concern that Jahmyr Gibbs' role in the passing game will make Raymond a non-factor in the Lions' offense. That concern is certainly warranted to some degree, with an overlap in where targets for each player will come.
But it's hard to imagine the guy who was second on the Lions in receiving yards last year (616), and was third in receptions (47), will completely disappear from the offense. Beyond Amon-Ra St. Brown, roles in the receiving corps are still in question, and hardly locked down even if the pecking order without Jameson Williams looks like it should be clearer now.
Raymond should be a more prominent part of that pecking order going forward, even beyond Williams' return from suspension.
