Unless you get bonus points for having your QB get hurt, having bad WRs or shifting up the O-line, that's all irrelevant for this discussion. When you're drafting a RB with a top 6ish pick and he ends up being the #16 RB, yeah, I'd say that's grounds for disappointment. I'm not looking at it relative to what he did prior, it's what he was expected to do that year, which is why you paid the high price. When guys under perform their draft slot by that much, it's a disappointment. It really shouldn't be controversial at all.
Just one last post on this point. And let me be clear that my point is about Chris Johnson's value, not about you. I'm sorry if it's coming off like I'm blasting you, especially for something you're not saying. That's definitely not my intention.This post right here, though, is specifically the sentiment that matters to me. I 100% agree with you that 2011 was a disappointment. Not a Trent Richardson, Doug Martin, CJ Spiller, Ray Rice or David Wilson kind of disappointment, but a disappointment nonetheless. When you pay a top five price for a guy and get RB16, you're going to have a hard time winning your league. It doesn't totally sink your season, but it sure doesn't help.
Where we seem to diverge, though, is in the value of discussing that disappointing season. You commented, "If you look at PPG or compare it to expectations, he hasn't been great lately. He was a stud his first 3 years, not so much the last 3." But as we've just discussed, if he hasn't been great lately, he's been close. He's put up remarkably consistent yardage - three years in a row within 30 yards of his average. His receptions and TDs have fluctuated, but he's been a poor RB1 or good RB2 three straight years. That might not be "a stud", but it's pretty damn good.
So what's the value of looking at his failure to meet expectations? I don't believe that there's any predictive value in comparing his ADP to his production. I don't think his performance will change one iota depending on whether fantasy football players in Wisconsin take him in the top 10 or outside of the top 50.
But there IS predictive value in looking at his past performance, and in looking at how people PERCEIVE his past "disappointments". Because it sure looks like people are going to discount him once again. And that's where his value comes from. He's an underrated player who should be a high end RB2 once again but will likely be drafted as a borderline RB3 and can be acquired at low end RB2 value.
Rotoworld's first blurb on him after he was signed was "The Jets get their man. Gang Green was the only team really showing legitimate interest in the 28-year-old six-time 1,000-yard rusher. Johnson visited with the Jets all day on Tuesday and said he had more visits to make. Either the Jets wooed him with more money to keep him from leaving town or Johnson simply didn't have any other clubs interested in him. In our opinion, Chris Ivory should remain the early-down back in New York with Johnson mixing in to see 8-12 touches per game. Johnson's fantasy value clearly takes a hit, if so.". Those are pretty low expectations for him. In a more recent post, they amended their projection to 12 to 15 touches per game, but reiterated "Johnson isn't going to be a true bell cow in New York". In other words, they're pretty pessimistic on him.
I tend to agree that his touches per game will go down. He's had a pretty steady 19-20 touches per game over the past three seasons, and I expect that to drop. But I also believe that his effectiveness per touch will improve. And that's where your comment "Unless you get bonus points for having your QB get hurt, having bad WRs or shifting up the O-line, that's all irrelevant for fantasy" is way off. I believe that it's entirely relevant when trying to predict how he will do with his touches. I believe that he's in a better situation and will get better opportunities (e.g. Ivory will take third and 1, but Chris Johnson will take third and long). If you predict a 20% decline in touches but a 20% increase in yards per touch, the numbers should stay close to even.
And to predict an increase in yards per touch, it absolutely helps to understand what he's trying to increase FROM. Johnson averaged close to 4.4 yards per carry in 2012, but 3.9 in 2013. It's meaningful that he was hurt in 2013, and that his line had massive turnover, and that his receivers sucked, and his QB got hurt, because it helps to explain why his numbers might have been down - and why we should project them to be better in 2014.
When we look at his decline from 2008-10 to 2011-13, it's meaningful to point out that the quarterback, offensive line and receivers all sucked during that timeframe, too. And that his best numbers came from working with a mobile quarterback who forced teams to play contain over here when the running back's over there. And that Ivory will help to improve his yards per rush by virtue of softening the defense and taking undesirable carries.
I find that much more meaningful than predicting him to disappoint because he's disappointed before. That's what your posts seemed to be advocating, but more importantly, it's what the rest of the fantasy football community seems to have done with him.
