Because it makes absolutely no difference. Efficiency measures incorporate the strength of opponent. Losing to a stronger opponent by less than "predicted" helps you more than winning over a lesser opponent by less than "predicted". That's there beauty. They make scheduling largely irrelevant.This turkey history explains a lot of the postings on this board.
Meanwhile, if net (small net) efficiency matters so much (difference between offensive and defensive numbers) why don't power teams (except for ticket revenue) go on the road (good for algorithm) and schedule weaker teams, driving their efficiency numbers up from the expected blowout? I guess they'd really have to be selective and pick middling lower teams that might end up with good records because of the TVI deal.
A question only JP could love.
Outperform the predictive model by losing close to to a higher rated team can help you more than beating a cupcake by fewer points than expected. And so it should be.
