I'm asking a question, not making a statement, because you do see a similar problem in other sports sometimes....someone once even quantified it, although it was over a longer schedule AND with much longer travel distances as well.
The logic is, when all of the other teams play each other, then they have shorter travel times for those matches so that the accumulation of travel over the course of the entire season is much lower for some teams than for others (BU, BC and Northeastern have shorter trips to each other than RPI would have to each one of them, for example). One team may wind up traveling hundreds of miles more than another over the course of the same season with the same common opponents. Of course, this problem would affect Notre Dame more than any other HE team and it doesn't seem to faze them!
As others have said, there may be compensating advantages which offset that situation, as well.....
