The Ohio State Buckeyes have turned into a Big 12 team before our very eyes.

They suddenly can’t run. They not so suddenly have a very average defense. They allow a ton of big plays.

And Saturday night, Purdue exposed every Buckeye weakness in clobbering Ohio State 49-20 at Ross-Ade Stadium.

It was a truly ugly loss for the Scarlet and Gray. Nobody will care that Dwayne Haskins smashed a bunch of school passing records. All they will remember is that this was the night when the Buckeyes went from a College Football Playoff contender to a team just trying to hang on to make a major bowl.

Here are some of the numbers to remember from a night to forget for OSU:

1: Inspirational story for Purdue. Honorary captain Tyler Trent is battling bone cancer and said that all he wanted was to see his beloved Boilermakers beat Ohio State. The brave young man got his wish.

2: Fourth-down conversions on two attempts for Purdue, including a fake field goal run. Coming in, OSU had allowed just two conversions on seven fourth-down tries all season.

3.0: Yards per carry for Ohio State. That’s the fourth consecutive game in which OSU has gained 3.2 or fewer yards per rush.

4: Consecutive games in which OSU has allowed at least 4 yards a carry. Purdue gained 161 yards on 29 carries, a 5.6 average which matches the worst for the Buckeyes this season.

5: Ohio State’s losses to Purdue since 1999. Only Penn State (6) has beaten the Buckeyes more often in that span.

5: OSU’s losses at Ross-Ade Stadium since 1999, the most of any road venue.

5: Players with 100 or more receiving yards against OSU in its past four games — including two for Indiana.

8.3: Average penalties per game against OSU, tied for ninth nationally. The Buckeyes had 10 for 86 yards on Saturday.

26: First downs for Purdue, the most OSU has allowed this season.

41: Yards on an interception return for a touchdown by Purdue linebacker Markus Bailey, who played high school football in Columbus, Ohio.

47, 73, 470: The pass completions, attempts and yards passing for Haskins. All are new school records, and none will cushion Ohio State’s fall in the polls.

170: Receiving yards for Purdue’s Rondale Moore

378: Yards passing by Purdue’s David Blough, the most the Buckeyes have allowed in 2018.

539: Total yards by Purdue. Again, that’s the most Ohio State has allowed all season.
