The Packers are very cabable to repeat, but they will have to overcome a few problems.
Congrats, Packers fans! We finally did it. It feels like it's been so long, back in 1996, with Brett Farve and Dorsey Levens. But they finally brought the title back to its rightful owner, its home. But while we are at home celebrating, the players, the coaches, and the staff, are hard at work, trying to make another "two-peat" happen since the last time they did it back in 1967 and 1968 when they won Super Bowl 1 and 2 under Vince Lombardi. But it's very posible, expecially for the talented team they have.
If they want to do it they will have to overcome a few problems. The first problem they will have to overcome is their injuries. Chad Clifton, Donald Driver, Charles Woodson, Ryan Pickett, Jason Spitz, Nick Barnett, Atari Bigbey, and Ryan Grant were all starters injured, and Erik Walden, Frank Zombo, and Korey Hall were all backups placed on injury reserve. With Ryan Grant back in action with the speed of James Starks and the elusiveness of Brandon Jackson, the Packers will be able to play "two-dimensional" game back to there game plan. And on the defensive side of the ball is Nick Barnett. When ever he is 100% healthy he is an animal. Also with him back their 3-4 defencewill be surpurb.
The second problem they will have to over come is there schedule. Being the Super Bowl Champs of 2010, thier 2011 schedule will be quite difficult. My main focus on their 2011 schedule is their rival games in the NFC North. Obviously the Bears are a team to fear , but dont underestimate the Lions and the Vikings. The Lions are a team on the rise and should be feared if they are on your teams schedule. They have the toughness and power of N. Suh on defense, and on offence they have the skilled wideout Calvin Johnson.
The Vikings are a good team, they just need to find the right quarterback. their defence are very physical and are really skilled in the secondary. So if they draft a quarterback like Jack Locker, they might be able to fix their offencive problems. He would fit in their type of offence, but would have to fight for the starting job with Joe Webb.
So all-in-all if the Packers can overcome their injures and their schedule they could very well repeat their "Super Bowl Season."
