Of course he will get blamed because he DESERVES some of the blame. What's funny is that you say it's never "The Packers" fault and yet Rodgers is the quarterback for said "Packers". You win as a team and fall as a team. I never said that these losses were entirely on Rodgers, but I sure as hell will give him a bulk of the blame to go along with the others. He's the leader, and it comes with the territory.
Even with the blunders on the defensive side, I noticed you didn't mention how Rodgers threw a boneheaded interception (should've been flagged for DPI) that lead to the touchdown going into the half which made it an uphill battle. When your defense intercepts the ball 2-3 times and you end up punting the ball, you have no excuses, especially for Rodgers caliber. Even then he still had an opportunity to win the game had he simply ran in to get closer, (he could've scored imho it would've been similar to Elway's helicopter against us in The Superbowl.) Was the situation ideal for Rodgers? Absolutely not, but why does everything have to be ideal? Rodgers has been in crunch time moments so why was it he couldn't capitalize.
When your defense holds a team to 13 points you have NO EXCUSES. People want to bring up his stats but if you ask me they're empty calories as they didn't result in points. The stats may show he did well, but by HIS STANDARDS he played pitifully. Missing throws, being tunnel vision and so on. I never said that Rodgers was entirely to blame but giving him a pass for his performance, but when he had the opportunity to stop the bleeding he failed. He's the one getting paid the big money, the FO listened to his demands and caved. ST has always been an issue in the regular season and yet he found a way to get the job done, so why couldn't he this time, especially when the defense that has been our Achilles' heel for years he wasn't able to stop the bleeding?
Fair or unfair, he had two chances to get the job done and failed. Were the situations ideal? No, but does everything have to be ideal in order for you to succeed? Heavy is the head that wears the crown.
