BYU is having struggle wins each week vs average to poor opponents (including a couple of miracles).
Notre Dame's only game decided by a TD or less was their loss to NIU. They have a 37 point win over ranked Navy (overrated but still), 49 point win over Florida St, 18 point over Georgia Tech (who beat Miami), 42 point win over Stanford, etc.
Indiana has one game this year decided by less than two TD's (Michigan). They have a 49 point win over Nebraska (who beat Colorado), 37 point win over Michigan State, 29 point win at UCLA, etc.
You might have a better argument with Miami - I see their resume as pretty similar to BYU's (better loss but BYU has better wins).
