Rams didn't just get wins this year, they were blowing opponents out. They are an excellent team. I think the change from Fisher to McVay has been night and day. Fortunately for them, they don't have to play in the same division as the Patriots*.
Buffalo has many flaws, and going form 7-9 to 9-7 isn't a huge turnaround. However, the turnaround is more drastic when you consider that all the experts were picking the Bills to win 2-4 games and said we were tanking. That will be glossed over by the media though.
It pains me to say it but Doug Marrone taking the Jaguars from 3-13 to where they are also deserves consideration. However, playing in the awful AFC South makes the turnaround much less impressive.
They are 1, 2, 3 for me.
