The Buckeyes were outplayed in every facet of the game at Purdue, losing to the Boilermakers, 49-20, in West Lafayette, Ind.It’s the first loss of the season for Ohio State, which falls to 7-1 on the year. OSU is still right in the College Football Playoff mix – the computer models still give the Buckeyes a solid chance of making it, especially if they win out – but a lot is going to have to change.Meyer spoke honestly about just what is going to have to change for the Buckeyes following tonight’s loss to Purdue.The main thing: Ohio State has to run the ball better.The Buckeyes totaled just 76 yards on 25 carries against the Boilermakers’ defense. Ohio State possesses two seemingly elite tailbacks in J.K. Dobbins and Mike Weber, but they combined for just 69 yards against this defense.“Down the stretch, we’re going to need a run game,” Meyer told reporters at his post-game press conference.This has been a common issue for Ohio State in losses during the Meyer era, too. The Buckeyes’ famously failed to get Ezekiel Elliott going in a home loss to Michigan State in 2015. Ohio State had more issues than just its running game tonight, of course, but it always seems to be a problem in defeat.Can that change moving forward?Ohio State will attempt to get things going again on Nov. 3 against Nebraska.
