Ready for the decline?

Dude..

Really?

You are already hoping we lose more games next year. Are you a closet packers fan hoping to jinx us?

You are an interesting person brother.
If you need to talk to someone send me a PM, Ill give you my number we can chat if you want?

What are the teams that dropped off? the chart spans from the 1978 to present...I would also like to know more context on all the teams. Injuries, FA's gained vs lost, players who might have retired.

Hard for me to judge the Bears next year going off this chart alone. I think they will be fine and have a similar type of year record wise, if key positions stay healthy.

First 6 games are probably going to have to be more on the Offense while the players/coaches on the Def are getting used to each other.

stats speak to populations not individuals (or individual teams).

The hook on this graph is the "equal or better record" the following year. 

Here's a couple links for some of the top one year turnaround teams

Some mentions from the links...

2004 PITTSBURGH STEELERS (6-10 TO 15-1)
Well yeah they probably aren't going to get 15-1 or 16-0 the following year...
BUT they did win a SB in 2005 with a shittier record, and then another one 3 years later. 

1999 INDIANAPOLIS COLTS (3-13 TO 13-3)
Still made the playoffs in 2000...they did dip in 2001 when Edgerrin James only played 6 games, but managed 9 playoff appearances and 2 SB appearances after that. 

2008 MIAMI DOLPHINS (1-15 TO 11-5)
Didn't do crap after this year but i do believe this year was just a weird coincidence. This was the first year of the WildCat.  

Take it for what you will, but the better perspective would be "teams success" for the following 2-3 years or more, rather than the "equal or better record" the following year. Like JABF said, even though he compares to NE lol, but they don't need a better record to have more success next year.
