What th-?

 OK, OK, O-KAY. Lemme see if I can get all of this straight:

* No. 5 Indiana lost to No. 4 Ohio State by the width of Nick Marsh’s foot.

* For the second week in a row, the No. 1 team — Georgia this time — lost on a walkoff field goal. At home, no less.

* Meanwhile the previous No. 1 team (Texas) lost AGAIN, also at home,  this time to a Florida team that had just been paved by 19 at home by an unranked South Carolina team.

* Also, No. 6 Alabama lost to Tennessee.

* Also, No. 2 Notre Dame flunked its first real test of the season, losing to  No. 8 BYU in Provo because the zebras swallowed their whistles and the timekeeper swallowed whatever it is timekeepers swallow on the last play of the game.

(Translation: Leading 28-24, BYU’s DBs knocked down a Notre Dame receiver in the end zone, stole his lunch money, kicked his schoolbooks into the gutter and made fun of his mom. Oh, and when the play ended with one second left, the timekeeper maybe/possibly was juuust a tad slow on the draw, letting the last second run out. Game over, BYU wins!)

Whew. What an insane, what-th? day in college football.

The No. 1, 2, 5, 6 and 7 teams all lost. The No. 3 team (Miami) needed overtime to beat Florida State. The nation’s two longest winning streaks — Indiana with 22 straight Ws and Notre Dame with 16 — both ended.

And about that Indiana game …

The Hoosiers almost pulled off another fourth-and-ain’t-gonna-make-it gamble, but Josh Hoover was crunched as he threw, and his 30-some-yard pass was offline by three inches or so, leading Marsh too close to the edge of the end zone.

And so Marsh stepped out of bounds as he caught what everyone in Bloomington briefly thought was another game-winning miracle by their Hoosiers. But it wasn’t, and Ohio State survived 19-15 in a game every bit as epic as expected.

It was a game Indiana, which never beats itself, probably beat itself, missing two field goals and turning it over twice. And it turned, really, in the second quarter, when Indiana, already up 7-3, drove to the shadow of Ohio State’s goal.

But on third-and-goal, Hoover failed to see Charlie Becker break wide open in the end zone. Instead he tried to squeeze a throw across the middle to Marsh, who was bracketed by three defenders.

Incomplete. And then Indiana’s kicker came on to cash the gimme 32-yard field goal, and he somehow spanked it off the left upright.

Make the right read, and it’s 14-3 and a very different game. Make the kick, and it’s at least 10-3.

Instead, Ohio State marched back downfield and scored on fourth-and-goal to take a 10-7 lead into halftime. The Buckeyes never trailed again.

And No. 4 survived. And No. 5 didn’t.

But, hey. At least they had plenty of company.
