I read the article at the first link, and frankly I am not sure there is anything of substance there. It's a pretty simple list of stuff that even an occasional fan might be able to tell you: the Packers' schedule next year is tough.
The writer seems to site the Tampa Bay game as reference a few times... but oddly enough (as tonyagnese stated above) make little mention to the second half of the season when he had games in Chicago, against the Ravens, and in Pitt. That's one heck of a brutal schedule that we actually seemed to have done pretty well in. At the very least, it shows this team can not only handle adversity, but they finally have a physicality about them that is much welcome and cannot be under-estimated.
Now really wanting to read the second link you provided because the first article doesn't really provide in the way of in-depth analysis or really different perspective. The article tries to be different-for-difference's sake, which isn't bad if done correctly.
A mention of things like how this team has pretty-much underperformed the last year and a half out of two years would've been a good start, I feel, at discussing the possibility of disappointment this season. Like it or not, the past eight games or so are an aberration under Ted's tenure.
That said, momentum can be an equally powerful force and we certainly had a lot of it at the end of the year.
