The 2020 NFL season will kickoff in September, with team beginning a 17-week march toward the playoffs. Between now and the start of the regular season, teams will - assuming no impacts from the coronavirus pandemic - open training camps, conduct preseason games, and, ultimately, whittle their offseason rosters down to the regular season roster limit of 53 players.
This year, in-game rosters will be a little different. There has been talk that NFL rosters were expanding to 55 players, and, in a way, it is. But, that is a game-day count of players eligible to be on the active roster for that week’s game, not an actual roster increase.
