I'm guessing that he's not actually pissed (or at least not more so than his usual state of being, which seems to be in a constant state of "someone has wronged me" - something that has served him well in his career), and this is all just a bit of posturing to try and gain some leverage for a contract extension that makes it hard for the Packers to cut or trade him in the next 3 years. Rodgers is a smart guy so he likely understands that demanding a trade is the only way he has any leverage in this situation. We've heard from (dubious anonymous) sources that an extension was offered, but we don't know the length or terms of it so it's difficult to really form much of an opinion on how reasonable the offer was.
I could easily see the Packer's front office trying to convince Rodgers to take a lower value deal due the circumstances surrounding 2020/covid/ reduced cap space. They would be borderline incompetent if they weren't taking this position.
I guess what I'm saying is this is likely a game of chicken from both sides. We'll see who flinches first.
It's disappointing that it has come to this, but I wasn't going to confuse Aaron Rodgers for Tom Brady when it comes to maximizing his contracts for personal gain. In the same breath, I'm not surprised and wouldn't blame the Packer's front office for trying to get a team friendly deal, and doing whatever they can to keep their options open with an aging QB that will undoubtedly have a very high cap number as long as he is part of the team.
There's a lot of hand wringing and manufactured drama going on here - it reminds me of the Russell Wilson trade story (or non-story as it has been so far) - so it's hard to take the situation very seriously at this point.
