3. CB Jerry Jacobs
Jacobs had a fairly rough outing against the Chiefs, with the fifth-worst Pro Football Focus grade among Lions' defensive players (59.8) and three missed tackles credited to him by PFF.
If we know Jacobs at all he is very disappointed by his showing in the season opener, and he will be driven to have a big rebound in Week 2 going against Seahawks receivers Tyler Lockett and DK Metcalf. He'll have to channel and harness any aggression he has though, so as not to make bad mistakes.
2. CB Cameron Sutton
As rough a night as Jacobs had against the Chiefs, Sutton was a bit worse in his first game as the Lions' No. 1 corner. He posted a 57.9 grade from Pro Football Focus (56.4 pass coverage grade), with two catches for 39 yards allowed (on five targets) and a 41-yard pass interference penalty that helped set up a field goal for the Chiefs to give them a 17-14 lead. That kind of performance won't cut it going against Metcalf and Lockett on Sunday.
The Seahawks' wide receivers, including rookie Jaxson Smith-Ngiba, certainly won't bail out mistakes by the Lions' secondary with rampant drops like the Chiefs' receivers did. Sutton and Jacobs both have to be way better on Sunday.
