There still are two games left in their season, but that hasn’t kept Green Bay Packers coach Mike McCarthy from weighing big-picture decisions entering a critical offseason for his team. With playoff contention off the table, McCarthy said Thursday he already is plotting how to lead the Packers back to the postseason in 2018. “I think you have to make sure you look at everything,” McCarthy said, “and be direct and honest and keep the emotion out of it. I think having two weeks to think about it will take the emotion out of it. We have to get better through the adversity that we’ve been through this year. We have to be honest about the patterns of negativity and positivity. “What comes from that, how do you learn from that, how do you improve? To win championships, you have to go through adverse moments. We’ve had plenty this year. Not hitting our goal, not playing to the standard of the Green Bay Packers, is definitely an adverse situation we need to learn from.” It doesn’t take much effort to recognize “patterns of negativity” with the Packers. One could be the franchise’s reluctance to maximize the potential benefit of free agency. Yes, general manager Ted Thompson signed seven free agents during the offseason, the most ever since he was hired in 2005. But none were the kind of potential difference-making additions competitors routinely consider. In fact, tight end Martellus Bennett was the lone unrestricted free agent. Bennett’s deal was structured to give the Packers a two-year option after his first season. Turned out, he didn’t even last that long.
