You can rationalize that 2/3 of the league is "close." It's all relative. The Packers did not compete with anyone in the NFC playoff field. They got run out of the building, threw together some scores in garbage time to keep the final score looking more flattering than it was. They were not losing those games 40-6, sure, but anyone saying they were ever really in that playoff game is wearing green and gold goggles. Minnesota and Detroit controlled them completely, twice.
I am not sure how anyone classifies them as a Top 5 team last season. They were not even the Top 5 in the NFC at year's end. Even if you look at several games the Packers won, they squeaked by some crappy teams. That's not even a criticism, just the reality that mediocre isn't that far off from good. I'd say the Packers were in the top 10 and literally 10th, behind KC, PHI, DET, MN, LAR, WAS, KC, BUF, BAL...and outside of that if you want to include LAC/DEN/PIT...I don't think those three were better, but I do think a healthy TB team was.
It would take some wild mental gymnastics to say GB was top 5 ahead of any of KC/BUF/MN/DET/PHI.
