Coaches blame a combination of factors for Packers’ quarterback Aaron Rodgers’ completion percentage taking a dive. The future Hall of Famer ranks 28th in the N-F-L completing a career-low 60-point-six percent of his passes. In four of Green Bay’s eight games, he has completed 60 percent or less. That compares with his career mark of more than 65 percent. Offensive coordinator Joe Philbin says there are no issues with the quarterback’s mechanics or physical limitations due to the knee injury.
