Except it largely is an every year thing.
There's three basic components a typical Iowa Football Season:
B1G West + Iowa State = Little-to-no HFA.
Solid teams = HFA, with the further they travel, the less likely they win.
Elite teams = A loss, occasionally pulling one out at home.
So in my estimation, HFA advantage comes into play...
- VS Indiana - Somewhat. If they're as good as advertised, not very much.
- VS Penn State - Little-to-none
- VS Oregon - Little-to-none
- AT USC - A LOT! Ferentz is 0'fer West of Lincoln in the regular season.
- AT Nebraska - Little-to-none
- AT Wisconsin - Little-to-none
Ultimately, how good they are (I don't think all that good) will determine the outcomes of Indiana, Nebraska, and Wisconsin; not where the game is played.
