Sure, the Goodship Pigskin has entered the dreaded gridiron doldrums, the slow, meandering depths of the spring and summer.

 

That just means it's time for us to dive into an icy bath of offseason Cold, Hard Football Facts.

 

Most of the free-agent moves have played out. Training camp is a couple months away. The draft is over. And all the rookie "pundits" – those who live under the delusion that their opinions matter – issued those silly draft grades last week.

 

Now we'll see if those moves made any sense, in our annual Cold, Hard Football Facts Fillability Index.

 

The pigskin premise of the Fillability Index is surprisingly simple, so simple that most people don't even bother to look into it: what have teams done to fill their statistical holes from last year?

 

The Fillability Index lets us know.

 

We've looked at the statistical profile of each and every NFL team from 2006, both in terms of common stats and our all-important Quality Stats, those stats that have a direct correlation to winning football games. We then looked at their off-season moves in the context of that statistical profile and then determined if each team has made the moves it needed to improve. For example, if a team has a great passing game in 2006 and loads up on wideouts, they have not fared well in our Fillability Index. If a team couldn't stop the run, but then packed their roster with beefy nosetackles and fireplug linebackers, then they have fared well in our Fillability Index.
