Saying that the Rams should have drafted Creed Humphrey or otherwise invested in the offensive line (something a lot of people have been saying for at least 2 years) is NOT the same thing as saying that the Rams' handling of the OL in the 2022 offseason was going to produce results like what we've seen this year.
I think the board was crystal clear that not drafting Creed was a WTF moment at the time.
The board then split between those who understand the intricacies of OL play and those who only know about it tangentially (like myself).
The former camp then began deep speculation into how the lack of investment could work out if everything turns out well. "Trust the coaches". "There's a chance because of xyz."
The latter camp, myself included, just went into meltdown mode because the writing on the wall was evident due to the lack of investment (i.e., common fucking sense). This frustration was crystalized into a common reframe - "we should have drafted Creed". This became a catch-all phrase for "we are fucked", and the casual deferred to the optimism of the experts because of "hopium".
So, I think your argument that the board didn't see this coming is
wildly misplaced. Even the most optimistic qualified their optimism, repeatedly.
And I'll even take all of this one step further by saying that the issue is that McSnead are reading their own press clippings and are greatly affected by their ego (i.e., not cutting underperforming draft picks, not resigning players they didn't draft, thinking they have a hallo effect on player development...).
It is what it is. I just hope Stafford, the warrior that he is, doesn't get seriously injured. Sadly, that too looks likely.
P.S. If I really cared I could show you past posts where I rallied firmly against relying on Brian Allen or resigned Brian Allen - independent of the Creed issue.
