FLOWERY BRANCH, Ga. -- Alex Mack has grown accustomed to the musical chairs along the Atlanta Falcons' offensive line in recent years.
The six-time Pro Bowl center enjoyed continuity during the 2016 Super Bowl run when the Falcons started the same five offensive linemen -- left tackle Jake Matthews, left guard Andy Levitre, right guard Chris Chester, right tackle Ryan Schraeder, and himself -- every game. But over the last 17 games, Mack has lined up next to six different starting guard combinations, including veteran left guard James Carpenter and rookie right guard Chris Lindstrom in a season-opening, 28-12 loss to the Minnesota Vikings.
