Here is what the article says, for the record.
Guided by Jim Larranaga, the Patriots were the model for mid-majors after parlaying a 2006 at-large bid into a Final Four run, upsetting
Michigan State,
North Carolina and Connecticut along the way.
They were not going to return to the Final Four anytime soon, but that was okay with everyone involved because “the Final Four was a magical situation,” said Tom O’Connor, who retired last summer after 20 years as George Mason’s athletic director. “And that magic doesn’t happen every day.”
It is Goff asserting that everyone (including Larranaga) was okay with not returning to the Final 4, not TOC.
How does the quote "The Final Four was a magical situation. That magic doesn't happen every day." mean TOC was okay with mediocrity or believed it was luck? Hint--it doesn't.
