While the Green Bay Packers appear ready to shift gears after their 6-2 start to the season, several former Packers are regretting their decision to leave Green Bay midway through the season.

Let's take a look at five players who will be green with envy (pun intended) about what's happening with the Packers this season.

The Packers and De'Vondre Campbell parted ways in the offseason, and the separation was unceremonious and partly public.

Campbell expressed frustration with how he was used in Green Bay and felt the Packers' plan did not bring him success. Meanwhile, the Packers were disappointed with Campbell's decline in performance since his 2021 All-Pro season and questioned whether he was worth the investment.

After leaving Green Bay, Campbell signed with the San Francisco 49ers, a team that appeared poised to make a serious playoff push. But instead of a revival, Campbell's game has regressed and more closely resembles its pre-2021 self than Green Bay's game-changing linebacker briefly enjoyed.

In just eight games, he has already missed eight tackles, coming perilously close to his career high of 11. He's a step behind when it comes to chasing ball carriers and seems to have lost the aggressiveness that once defined his game. Campbell's Pro Football Focus grade reflects his struggles – it's his lowest since his time with the Arizona Cardinals.

The Packers are now on the right track at 6-2 and appear to be a team ready for the playoffs.

As Green Bay's young core continues to develop, the decision to move on from Campbell seems more justified with each passing game. For Campbell, the move to San Francisco was far from the fresh start he probably imagined, and as his team stumbles to a 4-4 record, he may wish he hadn't pushed so hard to join Green Bay leave.
