You don't like historical comparisons. That doesn't mean they don't work, or that the people who use them are somehow risk-averse, concerned about saving face, or lazy. And besides, you use it yourself. When you talk about Michael Dyer and how #1 prospects coming out of high school often turn it around, isn't that an example of using historical comps? Is Michael Dyer identical to every other #1 prospect coming out of high school, and if not, how do you justify using them as comparisons when discussing Dyer's value? When you were high on Bryce Brown because of his high school recruiting ranking, how is that not a perfect example of using historical comps?
I believe in using all of the information available when making decisions. I use historical comparisons all the time.
What are you trying to determine when you're assessing an unproven young player for the purpose of gauging his expected remaining dynasty value? Obviously the situation is a factor, but in general I think you're trying to figure out exactly how good that player is. There are lots of signs that can help you reach an accurate assessment. Going back to my "where there's smoke, there's fire" terminology, the
fire refers to the player's actual value and the
smoke refers to the signs of that value. For example, the fact that a rookie RB was a 1st round pick, a dominant college player, and a workout monster are signs of a high value. Likewise, if a second year WR gets benched for two rookie UDFAs and doesn't catch a pass all season then these are signs that indicate low value.
That's all straightforward enough, but I also think it's important to recognize that smoke and fire ultimately aren't the same thing. When Marshawn Lynch was benched in Buffalo and traded for a modest price to the Seahawks, people like you looked at that smoke and determined that he was an average back. Hindsight tells us that those particular warning signs weren't actually indicative of his real talent level though. In other words, the smoke did not match the fire. Certain signs might be correlated with a player's actual value, but signs and actual value are two different things. You can be really good at reading the smoke and trying to predict what kind of fire is hiding behind it, but ultimately the smoke is just a means towards the higher end of determining the fire's nature.
I think if you look at the different ways FF owners go about trying to gauge the value of developing assets, you'll find that different people naturally gravitate towards different ends of the scale. Armchair scouts will often ignore a lot of the concrete objective signs because they think they can assess the fire without having to look at the smoke. So for example you get people thinking that guys like Isaiah Crowell are strong prospects despite a lot of smoke that indicates otherwise (i.e. Crowell was a UDFA and UDFAs rarely amount to anything). Some people do a little bit of both. This is where I would place myself. Part of the reason why I like Michael Dyer is because of the smoke (a 5 star HS recruit who put up strong numbers in his first two seasons at Auburn), but part of it is based on looking at the player himself and making an assessment of his skills. I have watched him extensively. I can explain in detail what I like about his skill set, physical tools, and running style beyond just citing surface characteristics. In the last group you have people who deny all armchair scouting (i.e. "if anyone could scout talent well then they'd be working for an NFL team") and make their assessments almost entirely on signs instead. I would put you in this category. I think you are a guy who basically looks at draft pedigree and situation, puts players in a box based on that, and then latches onto high ppg players after they have already revealed themselves as such.
That's not necessarily a terrible thing. I think sometimes it's useful to hear a reminder like: "Hey btw guys Percy Harvin is a ppg monster when healthy and you probably shouldn't forget that." Likewise, treating players like generic commodities can serve you really well in cases such as Kelvin Benjamin and Cam Newton where the FF community ranks a player far lower than where his draft slot and position alone would dictate. I remember years and years ago grabbing Larry Johnson (before his breakout) in the 7th round of a startup without ever having seen him play for the simple reason that he was a first round pick and thus might be pretty talented. That turned out to be one of my best picks in that draft. On the other hand, someone using this approach isn't actually evaluating players. He's just reading signs that may or may not be indicative of the player's true nature and banking entirely on that. When the signs don't match the talent, you're in for a rough ride.
I hate the "you disagree with me therefore you don't watch the games" arguments that armchair scouts throw out, but at the same time I strongly suspect that you haven't even seen more than 10 carries of Christine Michael in the NFL (including preseason) and that your opinion is based entirely on signs like his draft slot and Seattle's current depth chart. I've yet to hear anything specifically related to his skill set that makes you think he isn't a good prospect. Often times you'll be able to get away with that kind of analysis. In fact, I still think the best way to rank rookies is to sort them by draft order and positional importance with only minor adjustments made for subjective assessments of talent. On the other hand, if I turn on a game tomorrow and see some 7th round no-name rookie who looks like a complete animal, I'm not going to refrain from moving him up in my estimation just because the concrete signs might not yet dictate that behavior. Likewise, if I see a guy like Bishop Sankey looking like crap in the preseason, I'm going to run with that subjective assessment even if there are lots of objective signs indicating that he's a quality prospect.
I think this is where a lot of the disagreement about Michael comes from. One side says, "He looks like a beast every time he touches the ball." The other side does not believe in the value of subjective armchair scouting by amateurs and thus puts zero stock in anything related to it. Beyond that, I think there are different competencies in reading the signs, both in general and in specific cases. Some people are going to look at Christine Michael and say, "He didn't have great stats in college therefore he isn't that good." Others will look at the facts and say, "He didn't have good stats in college because he suffered two season-ending injuries." One group might say, "Christine Michael cannot beat out Robert Turbin on the depth chart. Therefore he must not be a great talent." The other might say, "Turbin didn't even get a single series to himself with the starters in the regular season tune-up. Michael played more with the starting offense and had more touches. Therefore Turbin is the backup in name only and Michael would play more if Lynch were to get injured."
Whether I'm right or wrong, if I think someone is doing a poor job of reading the smoke and that they have no ability or willingness to assess the fire itself then of course I'm not going to agree with their take on that particular player. This doesn't mean that I don't value signs. It means that they have to be used well and even then aren't necessarily a substitute for evaluating the player. When someone pulls out random comparisons like Chris Henry and Kevan Barlow to describe a player like Christine Michael who has massive differences in terms of production and/or physical tools, it tells me that they're likely just making a lazy comparison in order to serve their desired conclusion rather than approaching it from the perspective of, "What are Christine Michael's essential traits and which prospects from the past 10-15 years are most similar?" I give wdcrob some stick about his metrics-heavy approach, but the truth is that even if I don't agree with all of what he says, I appreciate the fact that he's at least casting a wide net and incorporating a lot of different criteria into what constitutes a "historical comparison." What I hear from the Michael skeptic crowd is typically very lazy stuff that doesn't go beyond the surface for maybe one or two traits. It's like putting up a neon sign that says, "Don't take my opinion on this player seriously." If you ask someone for a map of the city and they hand you a child's crumpled up crayon drawing, you're probably not going to trust that map. Not because you don't believe in maps, but because it's just a ####ty map.
