Undrafted free agent QB's don't get many chances to make their mark in the NFL, not when snaps behind center are so precious in practice and the regular season.

That's why the Atlanta Falcons first preseason game against the Baltimore Ravens is so important for Dominique Davis, who is trying to make the roster after finishing his collegiate career at East Carolina.

With Matt Ryan and Chris Redman likely locked into the top two positions, the competition for the third QB spot will come down to Davis and former Alabama QB John Parker Wilson.

Thursday will be Davis' best chance to show his stuff outside of a practice setting, as first and second-team players rarely play after halftime in the first preseason game.

More importantly, it will be a chance for the rest of the NFL to get a look at Davis. Even if the Falcons don't keep him, these preseason games will be his main selling point to the league's other 31 teams.
