When Rodgers left he got something like 75m guaranteed and like 38m/yr from the Jets. At his age and considering we had already added Love I don't think there was any way we were going to pay him that amount. Would he have stayed in GB for less? Maybe, maybe not. I think overall we got to the point where a change of scenery was going to be the best (and only) way forward for all parties. I can't speak for Rodgers or those inside the organization but I get the sense that while it was not the most harmonious thing, there doesn't seem to be a ton of bad blood either. I think if Rodgers stayed the mood would've really soured and it would've turned into a very messy divorce.
Adams I think was similar too in that the Raiders immediately went and made him the highest paid WR in football at the time. We would've had to give him the same contract AND they gave us a 1st and 2nd for him. I love Davante but to keep him you're basically "paying" a 1st and 2nd round pick (in that you would be receiving them otherwise) AND 140m+ to him. And in addition to getting to move closer to home, I think IIRC a large part of it was wanting to play with his best friend Carr too.
And I mean just think. Davante cap number has been something like 12-15m for the last few years (short Jets stint notwithstanding). This year our SEVEN wideouts carry a combined total hit of like...15m or thereabouts. Adding Rodgers' contract into the mix for the last few seasons, plus Davante on top of that...it radically reshapes our whole team. Rodgers had a cap number of ~9m and ~17m in two years with NYJ, but also dead money of 21m/35m, this year it is about 14-15m cap number with Pittsburgh. Similarly Davante had a cap number of 12/15m with the Raiders, but dead money of 14/16m, then just 3m with the Jets but 8m in dead money, and now 12m this year and 28m next year (with a ~16m out I think) with the Rams. All that to say, you would have a LOT of money tied up in a 40yr+ QB and a 32yr WR.
For better or worse, idk, but our team would look SIGNIFICANTLY different if we kept either one, let alone both
