The NFL has been turned upside down by one of the most eventful starts to free agency ever seen, and there's still more to come.
The Oakland Raiders seem to be competent again. The Cleveland Browns may very well be Super Bowl contenders. The Buffalo Bills look to have an exciting and emerging offense. The Pittsburgh Steelers appear vulnerable after decades of consistency.
What's going on?!
The NFL landscape changes quickly. Obviously, those teams deemed "winners" in free agency don't have a strong track record of success in the regular season. Even so, these moves are exciting and will have a profound impact throughout the league.
