I understand that one of changes with NET rankings is to no longer place different weights on late season vs early season games.there is no way to quantify how much different teams have been hurt by covid: from individual players missing games to schedule disruptions. The NCAA will have and, I hope use, more discretion than any season before. My hope is they over-emphasize the last month/tournaments. Go Buffs!
I disagree with your "no way to quantify" comment, and i think you're actually listing ways it could be measured. But that's not really important, IMO. I don't think the selection committee should try to consider team to team Covid impact when making whose in/out or seeding decisions.
