The Buccaneers were seven wins better in 2010 over 2009. The Rams and Chiefs were six wins better.
The Bengals and Vikings were six losses worse. The Cowboys were five losses worse.
Year-to-year results can vary wildly, as you can see from those record increases and decreases from 2009 to 2010.
Thus these strength of schedule numbers from ESPN Stats & Information are not packed with meaning. Still they are all we have to go on when looking at 2011's schedules in the context of 2010 results.
In the AFC South, things stack up in order. The best team has the "toughest" schedule, the worst has the "easiest."
This presumes, of course, a 16-game schedule based on the current scheduling formula. That could morph into an 18-game schedule with a new CBA, after which we'd have to rerun these numbers.
