Green Bay's linebacker math was already broken. Cooper just made it unsolvable.

The depth chart at linebacker tells you everything you need to know before you even get to the injury. Zaire Franklin handled 90 percent of the position's production last season. Kristian Welch handled the remaining 10. Whitney Mercilus is listed third with zero meaningful snaps to his name. That was the room before Edgerrin Cooper tore his Achilles — a high-need position by any honest accounting, with a production gap between starter and backup that ranked as one of the most severe vulnerabilities on the entire roster.

Now remove Cooper from that equation entirely. What remains is not a depth problem. It is a structural one.

I wrote last week that Green Bay's linebacker room was nearly gone. The Cooper injury doesn't change the argument — it confirms it, and accelerates the timeline. The Packers went into this season with two linebackers who had logged meaningful playing time. The typical NFL rotation carries three or more. Green Bay was already operating below that threshold with everyone healthy. The room was already being held together with tape and optimism. An Achilles tear doesn't just remove a player; it removes any margin the coaching staff had to manage Franklin's workload, to hide matchup problems, to rotate personnel and keep the defense fresh in the fourth quarter. That margin is gone.

What makes this particularly difficult to solve from within is that the names behind Franklin on the depth chart — Welch, Mercilus — have not demonstrated they can carry expanded roles at this level. Welch's 10-percent production share last season is the number that matters here: not as a criticism of the player, but as a realistic ceiling for what Green Bay can expect if Franklin misses even a single game. The Packers would be asking a backup who functioned as a situational piece to suddenly become a primary defender. That gap between what Welch has shown and what a starting linebacker needs to provide is not something a week of extra reps closes.

The broader context makes this worse. Green Bay's secondary is already operating without Micah Parsons, who remains out with an ACL tear. Brandon Cisse is questionable. The defensive infrastructure that was supposed to hold things together while the offense found its footing has been chipped away at, position by position, since training camp. My read is that the front office now faces a genuine decision: accept that this defense will be exposed in the middle of the field for the foreseeable future, or go find a linebacker from outside this roster. The current depth chart does not offer a third option.
