Packers: Top 5 lessons learned in Week 5 win over Cowboys

2. Mike McCarthy and the enemy within

The 12th-year head coach is Pittsburgh tough and showed his mettle by silencing many critics who were calling for his ouster during a four-game losing streak last season.

But McCarthy is still prone to making his share of impulsive decisions that get in the way of his team’s success.

His Week 5 blunder was an ill-advised call to attempt a 2-point conversion following (Damarious) Randall’s interception return that put Green Bay up by the score of 28-24.

An extra point would have put McCarthy in position to win the game by a field goal in the event of Dallas putting up 7 points on the on the subsequent drive.

Instead, the head coach opted for the 2-point play that would have given him a 6-point advantage, which wouldn’t have changed anything from the Packers holding a 5-point lead.

Was McCarthy influenced by his kicker, Mason Crosby, shanking two extra points earlier in the game?

Based on his track record and recent performances in clutch situations, Crosby should have been given another chance to tack on the additional point.

Otherwise, McCarthy called a solid game and gets credit for setting up successful running plays with effective pre-snap motions.

But with all that said, the coach’s one boneheaded 2-point try could have cost his team the game.
