I have been hearing nothing but bears and packers being the oldest and biggest rival. I have heard bear fans complain saying that they are the bigger threat to green bay. I have heard vikes fans say they are bigger rivals. But who do you really think is the biggest rival. Vikes and pack? Vikes and Bears? lions...? I think that the packers and the vikings is one of the biggest rivals and the bears are one to the pack but they dont compare. Maybe thats just me. What are your thoughts?
