There are a couple of things this suggests to me:
A) there aren't currently high enough levels of HN/PS to make a large impact on OF ratings, or
B) Tactics, opponent players' skills, and/or opponent's ratings affect OF, or
C) a combination of A) and B).
Yes, this is what I'm finding.
The puzzle to me is that if players like we are seeing on the T/L are being sold, I would expect the selling team to retain similar or better skills.
I think there is a 'D' and that is that PG skills have less impact on OF than the written rules state. That is, for example, instead of the 50%-60% impact it seems the written rules imply, perhaps there is a much closer to equal role for every player, in which case the PG is only 20% to 30% of the team's OF rating.
And all this speculation looks to be totally pointless given the game engine changes announced today.
Oh well. Now we won't even have meaningful history to examine after the ASB.
