I'll bet you both the Falcons and Dolphins take a step back next year-no doubt both were very good this year, but they overachieved with somewhat mediocre talent.
No doubt they have excellent coaching staffs, but they're going to feel the growing pains next year. As you've seen at times during the year and in that AZ playoff game, Atlanta's D was less than stellar(even the lowly Rams O was moving on them like clockwork the week before). Miami also has some gaping holes on both sides of the ball.
Ironically, in Tuna's first year in Dallas, he took them to the playoffs with a 10-6 record despite a very bad QB/RB, and a mediocre DL. Guess what happened the year after? Yep...6-10, and Tuna realized a year too late he had to scrap the entire 53 man roster. I can see his Fins go 5-11 next year. Oh-noodle arm Pennington isn't a long term solution, so he better get a QB in the draft!
