The Green Bay Packers are in crisis mode on the offensive line, and the front office is moving quickly to fix it. Green Bay signed Mekhi Becton to the practice squad after adding Laken Tomlinson off the Dallas Cowboys practice squad. On Wednesday, Green Bay also signed Kevin Zeitler. The Packers have already moved on from Cordell Volson, whom they had signed only last week.

That’s a lot of change in a short period. But with Tomlinson, Becton, and Zeitler in the mix, Green Bay can build a far more comfortable situation up front for the rest of the season.

The Packers had to act, but two spots that stay put

The Packers leaned heavily on Jacob Monk, Donovan Jennings, and rookie Jager Burton through the first three weeks, and the results have been damaging. Green Bay has the worst pass-blocking offensive line in football, with a 16% pass block win rate. No other team is below 30%, according to ESPN.

That makes it nearly impossible for Jordan Love to operate. The quarterback has been hit 20 times in three games, and the running game ranks as the worst in the NFL by EPA. The Packers now want veterans who know how to block and don’t need to be developed.

Green Bay is reasonably established at two positions, though. Jordan Morgan has played at a reasonable level at left tackle, and Sean Rhyan has done the same at center. Before the signings, they were probably the two best offensive linemen on the roster, so the Packers will likely leave those spots alone. The other three positions are open for a shakeup.

Left guard

The Packers have Aaron Banks as an option, but he has played only 22 snaps, all against the New York Jets, because of knee and toe injuries. He also dealt with injuries last year for the Packers and throughout his career with the San Francisco 49ers. That track record makes it hard to count on him. If healthy, Banks would still be an obvious upgrade over Jennings and Burton.

However, Tomlinson gives Green Bay a viable alternative. He knows the system after playing for the 49ers under Kyle Shanahan and for the Jets under Mike LaFleur, both of whom run a scheme similar to what Matt LaFleur runs in Green Bay. Tomlinson could start right away, and either he or Banks at left guard is the realistic ideal there.

Right guard

This was the biggest roster hole. Monk was the preferred starter in Week 1 even when everyone was healthy, and theoretically he would still hold the job. The Packers simply didn’t have great options.

The new signings change that, and Zeitler is the cleanest answer. He has almost 14,000 snaps at right guard in the NFL, and he gave up only 16 pressures for the Tennessee Titans last season. If he’s healthy and ready to go relatively soon, the veteran is the perfect fit for Green Bay at right guard.

Alternatively, Laken Tomlinson could also slide to right guard if Banks is healthy, although he has played far more on the left side throughout his career. Becton is another option if he is in shape after labrum surgery, a shoulder injury that affected him last year with the Los Angeles Chargers. He played right guard for the Philadelphia Eagles two years ago in the best season of his career, and he won the Super Bowl there.

Right tackle

Zeitler’s arrival also frees up Becton to move around. The former first-round pick was originally a tackle, playing on both sides for the Jets, mostly on the left. Packers head coach Matt LaFleur said after the signing that Becton could be an option at right guard or right tackle.

With Zeitler at right guard, Becton could serve as the backup there and also compete with Anthony Belton at right tackle if necessary.

The best realistic lineup

The best-case lineup would feature Morgan at left tackle, Tomlinson at left guard, Rhyan at center, Zeitler at right guard, and the winner of a Belton-Becton competition at right tackle.

That’s a lot of moving parts and a lot of ifs. Building a new offensive line during the regular season isn’t ideal, but the ideal scenario is already gone. The worst path would be keeping things as they are, because Monk, Jennings, Burton, and an oft-injured Banks are the problem, not the solution.

Even without much time to practice together, the jump in talent would be significant enough to turn a historically bad line into a normal bad one. For the Packers, their quarterback, and their running game, that would be a major improvement, and it’s probably the best they can hope for at this point.
