I wouldn't go so far as to call any decision made this year asinine. Minnesota will wind up playing 19 games, if their remaining four contests happen as scheduled. Over half of that schedule will be OSU and UW. OSU will play 18 games, and again, over half will be against UW and UM. UW will play 16, and exactly half of those will be versus OSU and UM.
My conclusion is that programs are trying to give their athletes as much of a season as is feasible, but they are prioritizing preparedness for a possible postseason over competitive advantages for the conference season. With the unbalanced schedules, it would have been possible to pick a standings method with greater fairness than what they chose, but a simple "total points" would not be a move in that direction.
