A breakdown of the Detroit Lions' 2018 free-agent signings:
The Lions signed center Wesley Johnson, who was a starter with the Jets last season. Here’s a closer look at the signing:
Grade: C-. Johnson may have been a starter with the Jets last season at center, but he was also the lowest-graded center by Pro Football Focus in 2017 -- No. 35 of 35. So it’s tough to see if he’s an upgrade over last year’s center combination of Travis Swanson and Graham Glasgow (when Swanson was hurt).
