Gah. Awful news for Hall owners. Did some reading today. Ryan Heath of Fantasy Points was letting go of some free material. I found this information. This is brutal and I urge you all to look at it. Ugly. YPC is a flawed stat but this shows the difference between Breece’s YPC when running a zone concept and when he’s running man/gap concept. It’s mind bottling. Anybody reprinting or restating should cite Ryan Heath. He deserves it. The new play callers are running zone concept. There’s a two-yard difference for Hall, and it ain’t in the good way.
So often these kinds of advanced analytics are dropped on the FF community like oracles of pure truth and so often they are garbage. I would advise all to be skeptical of any such study unless you fully understand the data and have full trust in its author. My livelihood is in charting complex and chaotic systems and using that work to build predictive models and almost always when I deep dive into these modern NFL analytics they are sloppy and terrible. Accurately charting football plays is super time consuming and requires lots of real football savvy and a highly trained eye and the people who make such studies are often closer to football tourists than true football professionals. When such a stat is produced almost nobody ever scrutinizes it, it just gets passed around like catnip for the lazy. I will openly state that I have not deep dived this Hall breakdown and it could be a careful and accurate study. But based on a lot of history and the basic sniff test I have questions about its quality.
Just for a fan of football, not even a football person, would it make sense that Breece Hall is wildly better at power gap running than on zone concept runs? Is he more of a big physical one cut runner or is he more of a patient, finesse runner who uses vision to set up his blockers? Unless you disregard the consensus of the entire NFL scouting community this result set is counterintuitive. Sometimes data can disprove a subjective human bias and provide a breakthrough in understanding. It’s possible that this has happened here but probably not likely.
Here's just one example of many on how these stats fail: what happens if on two of the power gap runs in the sample a key defender slipped and fell down in an unforced error allowing huge gains and this didn’t happen on any of the zone runs? Most of these models have no way of properly accounting for the true chaos of a football play which quite often leads to false signals and misleading results.
Sorry this got so long. I just see a huge blind spot in the fantasy community that gets passed along as wisdom and I try to comment on it where I can. Moving to more actionable commentary I’d say like others that I see some bad omens for Breece Hall this season in terms of snaps played and passing game usage projections. And the team knows the player better than we do so if they are talking about reducing his workload that should not be completely ignored. With all the bad juju, if folks are down on him or have him on the avoid list I think that’s reasonable. My eye tells me even after the injury Hall is still playing at a pretty high level, I just don’t see a player who is washed. In drafts I don’t mind making a bet on ability and taking Hall where he is sliding. There is reduced effectiveness risk and usage risk but Hall has gotten cheap enough where taking him still feels +EV to me. Even in the nightmare scenario where he’s lost half a step and he’s stuck in a full share with Allen with Davis sprinkled in, Hall is not priced wildly off his floor and he’d have contingent upside in unexpected scenarios like an Allen injury or a trade.
