I've seen this several times and every time I just can't believe it is true, but it is.
The Broncos would be 9-1 if they scored just 18 points in regulation of every game. They are 3-7 though because they just can't score. Even their wins they have scored just 11, 16, and 21 points. They lost to the Raiders scoring 23. Their other 6 losses have been 16 or fewer points. This is perhaps the most inept offense we've ever seen through 10 games. They are just awful and they have a HOF QB in his prime, and they are this awful. Just stunning.
I have been to three of their games and completely agree about the offense being completely terrible. Some of the worst game I have ever seen in person. The one that is pretty silly here is that russell wilson is in his prime. He definitely isn’t and was much better 2-3 years ago. Mobility is definitely down and his accuracy and arm strength have definitely decreased.
I think QBs like Brady, Brees, Rodgers, the Mannings a a few others have made people think that the new prime for QBs is deep into their 30's. But I think that faulty thinking, especially now and possibly going forward as running QBs become more prevalent.
First, those guys are statistical outliers. All-time greats tend to be. But there's a reason why Max Kellerman thought Brady's game was going to fall off a cliff so many years ago, it's because that's kinda the norm. Most QBs primes don't extend much past the very early 30's.
And with running QBs, who tend to get pretty beat up and not have really long careers, I don't think age 33/34(Wilson is just days away from turning 34)and beyond is a reasonable expectation for them still being in their prime.
It's probably best to look at things on an individual basis. For Russell, I think there's been a noticeable decline in his game the last two seasons, which makes sense since the prior 6-7 years, his actual prime IMHO, he took an absolute clobbering being the most sacked or nearly most sacked QB in that time frame. Add to that the hits he took running the ball, and it's understandable his game is starting to see a very real decline.
