I realize my name isn't Cyril, but I'll just pretend that it is.
And your skepticism is understandable Steve, because I'm assuming you didn't see Moore at Mizzou. And he's done next to nothing as a Falcon. He played in 1 preseason game (1 tackle), and 2 regular season games only on special teams (1 special teams tackle).

And then when you consider that Erik Coleman isn't a great fit at SS and is a much better FS then you understand that the team would like to see another player in that role. That player is Moore because IMHO, he fits very well in what this team asks its SS to do which is to play deep zone, cover TEs (mostly), and play the run up near the box.
He's bigger, faster, and stronger than Coleman, which means he should be a better matchup in coverage and a better run defender as well.
Not to mention that every 1st and 2nd round pick taken so far in TD's short tenure has been counted on to be a starter, one expects they will give the same opportunity to Moore in the near future.
