The NFL is a strange place, and the business behind the scenes is often just as odd. One minute you are getting ready to hit training camp, and the next you are gone.
The Miami Dolphins know a thing or two about unexpected change. They have watched as Ricky Williams abruptly retired before the start of the season and last year learned a valuable lesson when Shaquil Barrett opted to retire days before the start of camp.
Miami isn't dealing with that this year, but the Los Angeles Chargers are getting an idea of what it feels like after star receiver Mike Williams opted to call it a career on Thursday.
