Aaron's fine. He's not a god. He's a very good to great player, but he has several weaknesses. He can't and won't do it alone. He needs a defense and some slightly better coaching and scheming. Until the Packers field a defense that isn't largely pathetic, the Packers will not win another Super Bowl unless Aaron Rodgers plays like a god, which he did for most of the Packers winning streak, but even that probably wouldn't be enough. It's not a realistic expectation for him to do that though. It's great if it happens, but not realistic. It IS very realistic to expect a good defense that can shoulder some or a lot of the load, something the Packers either aren't willing to construct or are just incapable of doing so. Until that happens, it really doesn't matter what Aaron Rodgers does.
As always, Aaron Rodgers is the least of the Packers worries, and is the only reason they are anything more than a 4 to 6 win team that doesn't make the playoffs. That's not to say he's blameless, but it's all about prioritization because every team is going to have some weakness, or several. Much of this Packers coaching staff and administration wouldn't even be employed if not for Aaron Rodgers. Aaron pulls more than his weight, when will everyone else start pulling theirs? That is the question that needs to be asked. Perhaps Aaron Rodgers would do much less if he thought his defense was anything more than an embarrassment. He's unlikely to find out anytime soon, unfortunately.
