For the record:
At this point last year, the New York Jets were 4-6, one game worse than Miami is now, with a division record of 1-4. MikeO's advice to the team that made it to the AFC Championship game? Shut it down! You're done for this year.
Not at all. Because the "landscape" in the AFC was very different
last year. VERY DIFFERENT! Plus the Jets (per your example) held some tiebreaker options last year. They beat New England early in the season last year which gave them some bit of hope within the division and had other wins inside the AFC (Houston, Tenn..etc). Miami THIS year, lost tiebreakers to Pitt, Balt, and by losing at home to both Jets and Pats pretty much gave those tiebreakers away inside the AFC East.
If you can't see the difference you are putting your head in the sand and ignoring the obvious
