Why Randall Cobb Is Making Greg Jennings Expendable for the Green Bay Packers

The Green Bay Packers offense has been one of the most efficient in the NFL since Aaron Rodgers took over for Brett Favre in 2008 as the team's starting quarterback.

Every year since 2008—excluding this season—the Packers have finished in the top 10 in both total offense and points per game. The key has been Rodgers' ability to hit an interchangeable group of reliable targets.

While Donald Driver and Greg Jennings are probably the more recognizable names, wide receivers Jordy Nelson, James Jones and Randall Cobb, as well as tight end Jermichael Finley have all proven capable of making plays in this league.

With Driver on his last legs and Jennings oft injured, it is imperative that Rodgers is able to build trust with the many wideouts that have caught passes from him the past few seasons.

Nelson emerged in 2011 with 68 receptions for 1,263 yards and 15 touchdowns. And Jones already has seven touchdowns through six games this season.

But it is Cobb who might be the most important player to Green Bay's success right now.

While a much different player—serving a much different purpose—than Jennings, Cobb's presence allows Nelson, Jones and the tight ends to still work in one-on-one situations; very similar to what Jennings brings to the table.

Cobb is second on the team with 29 catches and 346 receiving yards. He also serves as the team's primary kick and punt returner, ranking in the top 10 in the NFL in return average in both categories—even returning a punt for a touchdown back in Week 1's 30-22 loss to the San Francisco 49ers.

The fact that Cobb is so dynamic is why the Packers don't need a true No. 1 wide receiver.

That isn't to say Nelson, Jones and Jennings aren't talented, it just highlights the fact that Rodgers is darn good at what he does too.
