I thought the games came down to one common thing. Home teams rolled.
In hindsight, I wonder if they had been at neutral sites how they'd have turned out. Now, my thinking is say Indiana-Notre Dame at say Soldier Field, or OSU-Tennessee at say Charlotte NC, SMU-PSU at say Giants Stadium, UT-Clemson at Nashville...that kind of thing. Keep them outdoors if the higher seed plays outdoors, reasonably close by to the higher seed to keep the weather element advantage there for them - but not on campus.
I know something like that is probably impossible to pull off, but if they had a near year to plan for all programs and sites (with a list of potential sites to choose from)...I do believe it could be doable.
