Marshall Newhouse was admittedly taken aback by the news. After playing every offensive snap at left tackle for the Green Bay Packers this past season, the decision was made to shuffle their offensive line next year to position their two best, Bryan Bulaga and Josh Sitton, on the left side of the line in Aaron Rodgers’ blind spot. Upon hearing the plan, the 6-foot-4, 319-pound tackle couldn’t help but think the team’s decision was reflection of his performance in 2012 and role in Rodgers’ 51 sacks last season. The coaches told him and the other three linemen involved in the move was simply to solidify the line, but the fact remained that he was out of a starting job. The move led to some initial disappointment, but Newhouse was soon grounded by one of the first phone calls he made to his father, John, who turned his focus to the next goal. Right tackle. “Just attack it,” John told his son. “You have to think of it as a challenge and rise to the occasion. There’s not much else you can do.” Newhouse took the advice to heart and returned for the start of organized team activities this week with the goal of controlling what he can control on the opposite side of the line. Offensive line coach James Campen was complimentary about Newhouse’s intelligence and fundamentals, but wouldn’t go so far to say on Tuesday the right tackle job belongs to the fourth-year lineman. With the addition of four new rookie linemen, the camp competition expects to be a highly contested affair as the team returns second-year tackle Don Barclay, who finished as the team’s starting right tackle in replace of an injured Bulaga, and drafted Colorado’s David Bakhtiari in the fourth round of last month’s draft.
