We won't know the status of every Atlanta Falcons player until later in the week. Some rookie players haven't been spotted on Flowery Branch's campus yet, as far as we know. The list of players that reportedly participated at one point or another in the team's player-run minicamp covered about half the roster, though there might have been even more.
However, the basics are covered. The Falcons two leaderiest (leaderiest) leaders, QB Matt Ryan and MLB Curtis Lofton, are confirmed to be reporting Tuesday, according to George Henry of the Associated Press. That's a day earlier than the date by which players have to check in.
Ryan is credited with having done much of the organizing work in putting those minicamp workouts together, and he and Lofton handled playcalling for their respective sides. Ryan has also spent time working and developing a relationship with rookie Julio Jones.
