ESPN has been ranking just about everything they can think of this offseason, and their latest effort takes a shot at ranking which teams improved the most, and which improved the least, over the offseason. How did they go about it? Well, they just asked some people who cover the NFL.
Keep in mind that this does not consider how good or bad a team actually is, but rather only how the roster changed since last season. Miami isn’t likely to top many lists this season, but the improvement bests the rest of the pack.
