FLOWERY BRANCH -- A quick roster analysis reveals that the Falcons are thin at the interior line positions and have no one who's started an NFL game behind center Alex Mack and left guard Andy Levitre after placing center/guard Trevor Robinson on the reserve/retired list on Monday.
The Falcons also lost Hugh Thornton to retirement over the offseason.
Both had NFL experience and were signed to minor make-good contracts. The Falcons also lost starting right guard Chris Chester to retirement.
Wes Schweitzer and Ben Garland are set to battle to replace Chester and neither has started an NFL game.
Robinson was excused from the offseason program to deal with a distressed family issue.
Robinson, 27, who played at Notre Dame, started seven games with Cincinnati (2012) and 14 with San Diego (2014-15) as a center.
Thornton, 25, signed March 21 after playing in 37 games and making 32 starts for the Indianapolis Colts after he was drafted in the third round of the 2013 draft.
Thornton, who played at Illinois, retired in May.
The Falcons signed Cornelius Edison, who played in six games with Chicago, but has no NFL starts.
The Falcons drafted Sean Harlow in the fourth round and signed undrafted centers Travis Averill and Cam Keizur. They also added guard Marquis Lucas, who's spent time with Buffalo and Minnesota.
The Falcons are converting Harlow, who played tackle at Oregon State, to guard.
With most of the 90-man rosters packed with players for training camp, there are no highly touted prospects out on the street with one exception. Former New York center Nick Mangold, a seven-time Pro Bowler with the Jets was released over the offseason. He's played in 164 games.
He missed eight games last season with an ankle injury. He visited with Baltimore in April.
