The Falcons should rotate the interior of the defensive line, but not everyone's getting equal snaps.
A year ago, the Falcons leaned heavily on Paul Soliai and Tyson Jackson at defensive tackle, with real snaps for Corey Peters and a smattering of snaps for Jonathan Babineaux (who was playing end) and Ra'Shede Hageman (who was a rookie) tossed in there. Everything has changed this season, even though the Falcons will return four of their defensive tackles.
Jonathan Babineaux played 695 snaps last year out of a possible 1,083, and now that he's a year older, that number will probably not go up.
