For a second straight week, rookie cornerback Josh Jackson was the Green Bay Packers’ highest graded player at Pro Football Focus.

Jackson, who had a pick-six called back by penalty, earned a grade of 95.7 on Friday night against the Oakland Raiders, just one week after he posted a grade of 95.2 in the Packers’ win over the Pittsburgh Steelers.

The Packers’ second-round pick delivered a pick-six that counted against the Steelers and was named to PFF’s Team of the Week for the second round of preseason games. He can expect the same honor this week.

Jackson beat out defensive lineman Kenny Clark for the top spot against the Raiders:

Two undrafted free agents vying for roster spots on defense also made the top five. Linebacker Greer Martini started in place of injured rookie Oren Burks and impressed, while safety Raven Greene – who forced a turnover on a fumble in the second half – finished with the defense’s fifth-best grade.

Reggie Gilbert, the Packers’ pass-rushing star of the preseason, cracked the top five for the third straight week.

Jackson, who also broke up a pass in the first half, now has PFF’s top grade among all NFL cornerbacks this preseason through Friday night’s games.

The marks weren’t as strong on the offensive side of the ball.

Rookie receiver J’Mon Moore, who snapped out of his funk with four catches for 62 yards, earned the offense’s top grade:

Geronimo Allison and Brett Hundley, who connected twice in the first quarter for 40 yards, rounded out the top three. Newly signed running back LeShun Daniels ran five times for a team-high 23 yards and earned a respectable overall grade.

The big surprise in top five was Spriggs, who played left tackle for the Packers’ highly disappointing second-team offensive line. While initial impressions of Spriggs’ work were negative, a rewatch of Friday’s game showed incremental improvements from the Packers’ former second-round pick. At the very least, he vastly outperformed right tackle Kyle Murphy, who struggled mightily at right tackle.

It’s possible Spriggs is now the front-runner to be the Packers’ top swing tackle behind David Bakhtiari and Bryan Bulaga.
