It's not ideal, but it'll only be a concern if this drags on for a while.
The Falcons have signed every rookie except for Vic Beasley, which brings us to an unpleasant little fact: Vic Beasley may not be at OTAs today.
Organized team activites are non-contact practices, and while it's ideal to have every player available, it's not the end of the world if Beasley and a handful of others aren't there. That said, a rookie first round pick who will be expected to step right into starter's snaps needs all the practice and time with the coaching staff he can possibly get.
