Because I never said "preseason play", I said "preseason record". These are not synonymous and barely even comparable.
I'm glad you mentioned this example because it illustrates my point perfectly. NE's offensive line struggling in the preseason is not unusual, it's virtually a rite of passage. You are taking a perfectly normal occurence and attributing post hoc significance to it based on events that followed.... which makes it a great representative of your entire post.
You must not have read the link I provided that demonstrated through collected data that the "preseason record" does have a statistically significant relationship to how teams do. For example, those who perform at 2-2 actually tend to do better in the regular season than any other record.
What you're stating is that the Patriots offensive line playing poorly is to be celebrated because it has happened before and is a "rite of passage." That is insane. We're putting Brady in danger by not having the pieces in place throughout the preseason and into the early weeks of the season. Just because Brady hasn't gone down since 2008 doesn't mean we just throw our hands in the air with the line the opening weeks until it's all good by mid-season.
Also, taking data and extrapolating from it is a pretty normal occurrence in sports, finance, box office figures, etc. If the Patriots line played poorly in the preseason, it would logically follow that they will struggle early in the regular season. I understand the concept of a post hoc logical fallacy, but this poor line and defensive play appears to extend directly from the preseason to the regular season. This isn't a classical post hoc example where I prayed for rain, it rained, so thus prayer made it rain. It is possible that their poor play in the regular season happened for reasons unrelated to their preseason play, but does that really seem likely? There were no major injuries or distractions.
It seems clear their struggles in the preseason this year carried over into the regular season. Your argument is "meh, they struggled before in other seasons, so they can struggle again this year and be golden." Maybe that's true, maybe it isn't. But while they likely will improve across the year if we take prior seasons with Scar, this poor line play still may cost them a game or two by week 8 and could result in an injury to Brady. Fingers crossed that doesn't happen.
Honestly, I'm struggling to understand why you are fighting so hard to dismiss the fact the Patriots poor play on the line (and defense) this preseason snowballed into the Chiefs game. Moreover, I'm not exactly sure why you tried to "ah hah!" me with the "preseason record" versus "preseason play" argument when I provided evidence that preseason records do have statistical significance. I get the feeling you just didn't bother to read my evidence because it was easier to keep attacking than address my points. I pointed out their 1-3 record in my initial post because it demonstrated a weaker effort than usual on the surface that also happened to be backed up by poor play by the starters in most games. If they went 0-4 resting their starters, I certainly wouldn't be on here being chicken little. But they did worse than usual while also playing most of the starters. Long story short: they didn't do well on paper or with the eye test.
I usually don't bother to dedicate such energy to responding to aggressive posts, but you seemed certain logic is on your side despite statistical evidence to the contrary. Overall I'm not really clear about what you're trying to debunk or why you are resisting facts.
