People are allowed to change their tune i.e. Farve. Relationships are complex, strain evokes distance and put down, but when it's all over and one has a clear perspective without resentful emotions getting in the way, true feelings emerge. I do think Farve will always consider himself a Packer first and foremost regardless of his divorce with the team.
The steelers impressed me with their last game and that has me wondering if GB can stop their running attack. BG already showed it can take exceptional special team players away, so I'm comfortable with that. What concerns me is the SB experience getting to Roger. I think Roethlisberger has a huge advantage in that department, having been there. Even so, I expect a very close game with GB coming out on top.
