Aaron Rodgers has started 96 games at quarterback, earned NFL MVP honors, led his team to a Super Bowl title and been named MVP of that big game. For all of Rodgers' service and accomplishments, what has oddly eluded the Green Bay Packers since he assumed the starting reins at the beginning of the 2008 season is having the same offensive line intact for an entire season. When Green Bay opens the 2014 season in prime time Sept. 4 at reigning league champion Seattle, the Packers will trot out a starting line that has again been retooled from the previous season. The only locks at this point, three months from opening day, would appear to be a trio of starting holdovers: David Bakhtiari at left tackle, Josh Sitton at left guard and T.J. Lang at right guard. Bryan Bulaga is back at his onetime starting spot at right tackle, but the fifth-year pro doesn't have as strong of a hold on the job as many would suspect. Bulaga missed all of last season because of a knee injury, paving the way for then-rookie Bakhtiari to emerge in what was intended to be Bulaga's spot at left tackle and young prospect Don Barclay to settle in at right tackle. Just because Bulaga is healthy again and has been able to go without limitations in the ongoing organized team activities doesn't mean Barclay, a third-year player, is the odd man out. "Donnie Barclay, to me, is a starting football player," coach Mike McCarthy said Tuesday as the Packers started their second week of OTA practices. "He's earned the opportunity to compete for a starting position. Him and Bryan will compete on the right side. We've got to make sure that we have as much competition as we possibly can." While Bulaga and Barclay wage one position battle the next few months, another showdown also is under way. This one has perhaps the biggest impact on the continued exploits by Rodgers.
