Ok, I'm not sure why we still have to have this discussion 20 years in, but Maxpreps does not generate the computer ratings. That comes from Calpreps. There is no 109-4 score on Calpreps for Lake Oswego.
Of course there isn't... They're in Oregon. Click any of the teams on that list, it takes you to MaxPreps. I don't even know why Calpreps list any Oregon teams anywhere.
