To say the Green Bay Packers have had a good offense for the past few seasons would be quite the understatement. The Packers' offense hasn't just been good, it's been one of the best units in the league.
However, Green Bay has the potential to become unstoppable during the 2013 season. Even with the loss of Greg Jennings, the Packers' offense should be the best it has been in years.
Let's take a look at why this group should be unstoppable in 2013.
A Ground Game
This is the area of Green Bay's offense that has been lacking since Ryan Grant rushed for over 1,200 yards back in 2009. Since that season, the Packers have finished 20th (2012 season), 27th (2011 season) and 24th (2010 season) in total rushing yards in the NFL.
While this isn't a team that is ever going to lead the league in rushing, they do need to be able to take the pressure off Aaron Rodgers at times. That hasn't happened, which has allowed defenses to hone in on slowing down the passing game.
However, the Packers should be much improved on the ground for the 2013 season. Along with DuJuan Harris and Alex Green, Green Bay added two potentially studly running backs in the draft in Eddie Lacy and Johnathan Franklin.
Even if the Packers don't find an every-down back, they still have enough talented to get a tremendous amount of group production. Don't be surprised if this unit becomes one of the more productive units in the league by seasons end.
Evolution of Randall Cobb
The man who is going to be relied upon most in replacing Jennings' production is going to be Cobb. The second-year player finished just shy of 1,000 receiving yards last season with 954 and eight touchdowns.
Cobb certainly isn't as polished of a player as Jennings, but he is was more dynamic and a much better playmaker. He's the type of offensive player who is a threat to score every single time he touches the football.
The scary part about Cobb is that he is only entering his third season, so there is still room for growth. His evolution was a big reason why the Packers felt they could move forward without Jennings and still be successful.
Unfortunately, Packers' legend LeRoy Butler may not feel the same way.

It's true arrogance to think there is another Greg Jennings , Randall Cobb is awesome,but he is going to need help,2/14/2013, 1:40:12 AM
However, Cobb won't only replace Jennings in terms of production, he'll eventually become more productive.
Improved Offensive Line
This might be shocking, but an offense won't be very good if a quarterback is always laying on his back. Rodgers was sacked a ridiculous 51 times last season, the most he's ever been sacked in his career.
Changes and improvements definitely needed to be made. While the Packers didn't make any big splashes via free agency or the NFL draft, they made in-house changes that should bring about positive results.
They're moving right tackle Bryan Bulaga and right guard Josh Sitton over to the left side of the offensive line. Marshall Newhouse, who played left tackle for the past two seasons, graded out as the 54th-best offensive tackle according to Pro Football Focus (subscription required). That isn't good, so it was definitely time for a change.
Tom Silverstein of the Milwaukee-Wisconsin Journal Sentinel spoke to head coach Mike McCarthy after the switches were announced, and this is what he had to say concerning his confidence in Bulaga:
"I wouldn't have done it if I didn't have full confidence in Bryan," McCarthy said. "He's been here everyday (in the off-season) and so I've seen him develop physically in all areas of his game. He's a very mature player."
Clearly, McCarthy feels that Bulaga can be that franchise left tackle that Rodgers desperately needs.
With an improved offensive line that will actually give Rodgers time in the pocket, the sky is literally the limit with this offense.
Still Plenty of Weapons
Even if Cobb didn't improve and the running game stayed the same, this is still an offense that has players like Jordy Nelson, James Jones and Jermichael Finley.
It really isn't even fair when you look at all of the weapons that the Packers have on offense. If a defense wants to try to shut down Nelson, Rodgers will simply hone in on Jones or Finley or Cobb.
There isn't a defense out there that has the personnel to slow down all the offensive playmakers that Green Bay can throw in the field at one time. The Packers' weapons are always going to outweigh the defensive playmakers.
With an actual ground game, Randall Cobb taking the next step, an improved offensive line and a handful of weapons, the Packers' offense simply has no other choice but to be unstoppable in 2013.
