Rosters around the NFL are about to look a whole lot different. Though free agency won't officially open until 4 p.m. ET on Wednesday, teams can begin contacting players agents as early as 12 p.m. ET on Monday. For many of the top players, the first date is more important than the second.
Where the league's biggest stars are concerned, coming to an agreement is often just as important as finalizing a deal. Though there is a chance that either side can back out before the official start of free agency, it's a bad look for teams or players to do so.
