Rodgers didn't just have one season of mediocrity. Its been a few years. Here's how he ranked:
2019: 21st in completion %, 14th in TD%, 17th in YPA, 12th in QB rating, 18th in QBR.
2018: 26th in completion %, 22nd in TD%, 17th in YPA, 13th in QB rating, 20th in QBR.
2017: 8th in completion %, 2nd in TD%, 17th in YPA, 8th in QB rating, 10th in QBR
2016: 4th in completion %, 2nd in TD%, 13th in YPA, 4th in QB rating, 4th in QBR
The only metric where he continues to be elite is with turnovers, where he very rarely throws interceptions.
He was an elite QB in 2016, he was a top 10 QB in 2017, and he fell off a cliff the last two seasons. You'd be hard pressed to find a metric, beyond turnovers, where he was even in a "good" category. His completion %s are atrocious for a modern NFL QB, he has consistently been a guy who hasn't thrown the ball down the field at all for several years now. And while I think stats like QB rating or QBR are largely irrelevant, there's plenty of metrics that will show this.
Its not a lifetime achievement award. He wasn't viewed as a top 3 or even top 10 QB the last couple years because literally nothing he did on the football field was indicative of a top 3 or top 10 QB. Yes, the offense sucked. He also plays on that offense, and he wasn't any good either. He's been playing with a bunch of nobodies for a few years now, and now all of the sudden he has studs around him? I don't think so.
