narrative fallacy makes absolutely no sense to me as a descriptive term
The narrative fallacy is something we all fall into at times but is how most bloggers and sports journalists make their living. Better explanations can be found if you google it or read the original arguments via
Taleb, but here's my poor short explanation.
Human mental processing depends on putting things into stories so we can comprehend them logically. If you take a bunch of random facts, ie. Seahawk draft day trades, then you will naturally be drawn to compose some sort of story around them that resolves many complex separate facts into one understandable idea. The problem of course is that 15 distinct trades do not actually equal one understandable idea, hence the narrative fallacy cautions about overconfidence in how we design stories around those events.
They have a track record of repositioning, to pick players they are smitten with, regardless of where the pick is
What you actually have is a record of draft day trades they have made. Interpretations about whether they are "smitten" with particular players and how that has affected those trades is a narrative attempt to turn those facts into something more actionable. Maybe you are right and maybe you are wrong, but you're assuming the conclusion on an important point.
It's also not meant as a personal attack, rather a reminder that jumping to conclusions about what we think we know from the outside is often flawed. In my view, tiered drafting also explains their moves and is what every NFL team describes as their process. You can also see the tier lists on the boards behind them at times.
Teams do not reposition their draft selection to get into a "tier" unless they are smitten with every player in that "tier" or believe a position of need can be guaranteed to be filled within that "tier". In all other cases, it makes no sense to move your pick on draft day if you are confined to a "tier" mentality
It's a gamble that every team does to pick up some value. In short, the Hawks may be picking at #25 and they see they have 6 players left all about in the same tier. They could drop down 10 spots and have a pretty good shot of one of those players falling to their pick. Similarly, if the last player from a previous tier is still there at #23 then that's a great reason to jump up two picks.
I suspect there's also an unwritten confidence parameter assigned to every pick that influences the actual decisions, which may be partly what you're referring to.
Teams will, and often do reposition in the draft for specific PLAYERS
I don't follow this point. Trading down if you are fixated on a certain player is something you would not do because you have no idea what the draft boards of 31 other NFL teams looks like. Trading up is easily explained by the player being the last one in a given tier and position group.
In other words, if we were targeting Metcalf then how could we have known he would be available at #64? Letting him fall seems like a clear indicator of drafting for tier value and then taking BPA when he was available.
