Green Bay Packers head coach Mike McCarthy has pinpointed his team's struggles on poor fundamentals. Even his All-Pro quarterback, Aaron Rodgers, needs to go back and brush up on the basics.

When asked what causes Rodgers' fundamentals to break down, McCarthy said his signal-caller may be "trying to do too much," according to Ryan Wood of Press-Gazette Media.

Rodgers is one of the best quarterbacks to ever play the game, but he's surrounded by a subpar supporting cast this season. His receivers can't create separation consistently, he's not getting much help from the ground game and the health of his offensive line is never ideal.

As a result, Rodgers is holding onto the ball longer and getting hit more often. He has been sacked 11 times during the Packers' three-game losing streak, which has in turn affected his completion percentage (63.3) and yards-per-attempt average (7.25).

Rodgers still has respectable statistics on the season -- highlighted by 21 touchdowns and only three interceptions -- but he hasn't been as dynamic during Green Bay's current skid. The Packers need him to focus on his job and hope his playmakers start to come along in the second half of the season.
