If you perform the 2015 San Francisco 49ers offseason to the Packers, here is who you lose:

Green Bay would have lost Mike McCarthy, Jordy Nelson, Jarrett Boykin, Jeff Janis, Eddie Lacy, Josh Sitton, Bryan Bulaga, Don Barclay, BJ Raji, Nick Perry, Mike Neal, AJ Hawk, Brad Jones, Tramon Williams, Sam Shields, Demetri Goodson, and Tim Masthay.

Frightening part is, they have lost four of them on their own (Nelson, Boykin, Hawk, Jones and Tramontana). Plus Goodson is hurt.

You can do this with any team: http://www.sbnation.com/nfl/2015/9/4...-as-the-niners
