PFF FA Grades so far

DETROIT LIONS
S Tracy Walker: Three years, $25 million ($17 million guaranteed)
If Walker?s PFF grading profile over the course of his NFL career was viewed in reverse, this contract would look likely be seen as a steal. After earning an 82.5 overall grade across his first two years in the league, that mark has fallen to 57.1 over the past two years. He?s been at his best in coverage when operating from deep alignments as the free safety. The worst season of his career came in 2020 when he was asked to play closer to the line of scrimmage.
With holes across the roster, Detroit opted to lock in one of its more productive defensive backs across the past several seasons. The team could still stand to add some more quality depth at safety in the coming weeks.
Grade: Average
WR D.J. Chark Jr.: One year, $10 million fully guaranteed (up to $12 million)
Chark missed the majority of the 2021 season with a fractured ankle, but there should be no long-term concerns, and he?ll still be just 25 years old in Week 1 of the 2022 season. Chark earned a career-best 75.8 receiving grade in his sophomore 2019 season, going over 1,000 receiving yards with just two drops on 114 targets.
The LSU product is every bit of 6-foot-4 and ran a 4.34-second 40-yard dash, a true big-bodied burner on the outside. He has skills that simply cannot be taught. The Lions did very well here to get him on a one-year flier, providing a huge boost to their offense. And now Chark can also play his way into a substantial multi-year deal next offseason.
Grade: Above average
Edge Charles Harris: Two years, $14 million
Harris put together a rewarding contract-year breakout for Detroit last season, earning a 78.7 PFF pass-rushing grade on 871 defensive snaps. It was the first time he cleared 500 defensive snaps in a season, and his 52 quarterback pressures were more than he recorded in his previous three seasons combined.
That kind of jump tends to be dangerous when it comes to contract extensions from the team?s perspective, but this looks to be a reasonable deal for Detroit. Harris can get to the quarterback from wide alignments, and the Lions aren?t exactly flush with pass-rushing options as of now.
Grade: Above average
