COLUMBUS (AP) -- Angry with the way his defense played in its last three games, Ohio State coach Urban Meyer is urging his players to attack more and think less.
"It's a fast-paced game (with coaches dealing with getting players) lined up as opposed to it used to be a game based on effort," Meyer said. "And I want to get back to that."
The Buckeyes held their second practice of the spring Thursday, and as will be the case throughout the 15 workouts the emphasis is on relying on instinct and playing without restraint instead of following the diagrammed play and reacting.
Ohio State surrendered an average of more than 38 points and 539 yards a game while closing out 1-2 in the most important games of 2013. With seven starters back from that unit, Meyer is demanding that, first and foremost, everyone play hard and fast.
The defense had a collapse of epic proportions near the end of a program-record 24-game winning streak, all under Meyer in his first two years on the job.
His coaches have been put on notice that things will be different.
"It was a combination of things," co-defensive coordinator Luke Fickell said about the problems. "When things start to go and you lose confidence in what you're doing, it's tough."
They beat Michigan 42-41 on the road to get to 12-0 late last November, but then suffered a 34-24 loss to Michigan State in the Big Ten title game and a 40-35 setback to Clemson in the Orange Bowl.
The Buckeyes allowed 161 yards rushing per game, but absolutely gushed yardage when the other teams passed. Michigan completed 32 of 47 passes for 451 yards without an interception. The Spartans were 24 of 40 for 304 yards with one pick. And then Clemson completed 31 of 40 for 378 with two interceptions.
Linebacker Curtis Grant said things had been simplified so far this spring.
Meyer's biggest concern is the linebackers, who didn't necessarily have a good year -- and that was with an All-American in Ryan Shazier. Now Shazier is gone, leaving early for the NFL draft, and Grant and Joshua Perry are the returning starters. They'll be pressed for playing time by many others.
Almost all of the line is back, led by Michael Bennett, Adolphus Washington, Joey Bosa and Noah Spence. The secondary is missing starting corner Bradley Roby, who also left early for the draft, along with safeties C.J. Barnett, Corey Brown and Christian Bryant.
Two new defensive assistants are on staff. Larry Johnson, late of Penn State, is now the assistant head coach/defensive line. He took the place of former Buckeyes player Mike Vrabel after he jumped to the NFL to take a job with the Houston Texans.
Chris Ash, also familiar with the Big Ten from his years at Wisconsin, took over as co-defensive coordinator/safeties and is the nominal replacement for Everett Withers, who became the head coach at James Madison.
There are options, particularly at linebacker.
Raekwon McMillan, one of the nation's top recruits, figures to get a look right away. So will fellow incoming freshmen Kyle Berger, Dante Booker and Sam Hubbard.
