The game was close on the scoreboard but it rarely ever felt close on the field. Yes, the returns happened but the Hurricanes were (for the most part) dead in the water beyond their return game.
The Return game is absolutely a valid way to score but it doesn't represent sustained high quality play the way that offensive potency does. Hence, it was close on the scoreboard - but once OSU started to kick off to the upbacks and towards the sidelines, it never really felt close again on the field.
Dominant win, IMO.
