The Green Bay Packers did a bold thing when they kept seven wide receivers (and only three inside linebackers) on the 53-man roster at the end of final cuts.

After struggling on offense last season and dealing with injuries to multiple pass-catchers, the Packers clearly wanted to keep their homegrown talent on their roster and off other teams', as many players likely would not have gotten through waivers to be placed on the practice squad.

However, for a team that has seven wide receivers at its disposal—all of whom are active on game day, given their roles on special teams—the Packers sure aren't using them much on the field.

Green Bay's offense has continued to look sluggish and, frankly, vanilla through the two games to start the 2016 season, a worrisome continuation of a problem that plagued the team through the entire 2015 season and into the playoffs earlier this year.

Mike McCarthy continues to be at the helm calling plays. Jordy Nelson is back in action. Ty Montgomery is healthy. Davante Adams is working on his drops. The Packers, for the first time in a long time, have an athletic tight end to threaten the seam.

So what's the problem?

While you can never fully remove execution from the equation—Adams has still dropped a couple passes, Nelson still seems a little off, and Aaron Rodgers looks plain overwhelmed at times—the problem, at its core, seems to stem from the offensive game plan.

Scheme vs. execution is an age-old question. And the Packers' scheme is the Packers' scheme. There's not much use pointing out its flaws, because it's not going to change as long as Mike McCarthy is at the helm.

But it's worth mentioning before we get deeper into personnel groupings and coaching decisions that the Packers run a spread-based offense that uses isolation routes, where receivers, who are spaced far across the field, have to beat their one-on-one coverage in order to get open and make the play.

Aaron Rodgers, at the beginning of any play, will receive the snap and analyze the defense as he progresses through his reads. He has a hot read, a second read, a third read, etc. Whichever of his receivers appears to be winning his route is the one Rodgers will target.

Because their scheme is heavy on isolation routes, the pass-catchers have to win man coverage.

But often, they don't, especially in the last year. When that happens, the play can fall apart real fast—and that's when you see Rodgers running around in the pocket, trying to extend the play, and sometimes just taking off with the ball himself.

The Packers don't use a lot of pre-snap motion. They don't run a lot of designed crossing routes. And the offense is starting to look a little vanilla for it.

But this is the Packers' scheme, like it or not, and they've had immense success within it in the past. They have set NFL offensive records with it. They have won a Super Bowl with it.

Yet NFL defenses have continued to evolve. Some coordinators and coaches, like Minnesota's Mike Zimmer, meet the Packers so often that they can perfect a strategy to stymie Green Bay's offensive attack.

If the Packers aren't going to alter their scheme, they can at least get creative with their personnel groupings.

The base personnel for most NFL offenses is the 11 package, featuring three wide receivers, one tight end, and one running back.

For the Packers, this is their "Zebra" package. McCarthy loves it because it is what allows the team to utilize the up-tempo, no-huddle offense so effectively.

If you're keeping the same 11 players on the field, you can run at a higher tempo. But in so doing, you sacrifice versatility and creativity in offensive looks.

That doesn't mean those players are always doing the same thing. In the "Zebra" personnel with Jordy Nelson, Randall Cobb, Davante Adams, Jared Cook, and Eddie Lacy, you can have Cobb in the slot or lined up in the backfield. You can have Cook split out wide or in to block. You can have Nelson as the outside X receiver or even in the slot, if Cobb is in the backfield.

The Packers can and do often mix up where they line these base players up on the field.

But that's only three of seven active receivers seeing a significant chunk of action on on the field. Per ESPN Stats & Information and via Rob Demovsky, so far this season the Packers have used their 11 personnel on 69.9 percent of their offensive plays, and three-receiver sets in general on 77.2 percent of their offensive plays.

On 84 of 95 offensive snaps, those three receivers were the same three players: Nelson, Cobb, and Adams.

Meanwhile, not counting special teams, Jared Abbrederis has played 20 snaps; Ty Montgomery, 11; rookie Trevor Davis, five; and Jeff Janis has played only on special teams as he's currently wearing a club cast.

It makes sense that the Packers want to keep their tempo up; doing so can tire out defenses and make them easier to diagnose. But their offensive creativity shouldn't suffer as a result.

McCarthy, offensive coordinator Edgar Bennett, and Rodgers—who works in tandem with McCarthy on play selection and, like most elite quarterbacks, has the option to opt out of a play based on what he sees on the defense—need to work in some of their other weapons.

Have Abbrederis run a go route. Bring in Cook to threaten the seam. Use Davis and Cobb in both slots. And do a better job establishing the run so that the passing game can have success. In the 2010 season, when the Packers won the Super Bowl, they were running four-receiver sets often, and even their "big five" receiver set. That worked out pretty well in the end.

Right now, this offense is too predictable, and we saw how that worked out for the Packers last year.
