The weakest position on the Packers roster heading into the preseason was inside linebacker. Through the first game, that hasn't changed.
Due to the struggles with talent at the position, the Packers will likely keep an extra inside linebacker on the final roster. That final spot was likely going to second-year player Sam Barrington.
Of course, that was before undrafted rookie Joe Thomas stepped on the field. Thomas has excelled during training camp, the Packers' Family Night and was a standout performer during his first preseason game.
He luckily avoided major injury in that game, according to Rob Demovsky of ESPN.com, which is good for his future in Green Bay. As for Barrington, he's going to need to really flash on the field to catch up to Thomas.
This will be the hardest cut the Packers have to make due to Barrington's age. However, the Packers need players who can produce at inside linebacker, and right now Thomas is the one showing he can do that.
