COLUMBUS, Ohio -- The future hasn’t arrived yet, but it’s no longer just the Ohio State coaching staff thinking about what it looks like on the offensive line.

The four seniors heading for the exit and about to usher in a new era are now every bit as aware that the end is near, leaving them two different legacies to attend to at once before they leave behind all of those starting jobs.

The ramifications on their own careers with the No. 7 Buckeyes are obvious as they look to cap a banner two-year run in the Discover Orange Bowl against No. 12 Clemson on Friday. But looking beyond that, the veterans have balanced their preparations for one final game with the need to get some younger guys ready for what comes after it at a position that has become the backbone of the program thanks to that core group of four.

“I think as you start to look around and it’s coming to an end for us, you realize that you do have a lot of responsibility to make sure this place is OK when you’re gone,” left tackle Jack Mewhort said. “I think us as seniors, I’ve been trying to coach guys more than I ever have and making sure that guys are getting ready.”

There will be one familiar face still around, with Taylor Decker serving as a bridge from the present as the Buckeyes begin the transition and rebuilding of the critical unit up front.

The sophomore right tackle more than held his own with his senior teammates on the close-knit offensive line, and his experience playing alongside them could be invaluable as he suddenly becomes the elder statesman in the meeting room. The Buckeyes have also had a recent glimpse at Pat Elflein in competitive situations as he was pressed into duty at right guard following Marcus Hall's ejection against Michigan and subsequent discipline in the Big Ten title game, and the right side of the line appears to be in good hands if that’s where both he and Decker end up staying.

Jacoby Boren has also impressed on the practice field and in limited opportunities to play in games at center, though plugging him into the starting lineup would still leave a couple more holes to fill heading into spring practice. And since Mewhort, Hall, Andrew Norwell and Corey Linsley won’t be around then to offer any advice to potential candidates to fill those spots, they’re getting all the pointers they can in now.

“Just from a teaching standpoint, it’s just all about helping them out, where we see their weaknesses are,” Linsley said. “If we can point out, like, I don’t know, Billy Price needs to learn to keep his pressure on the inside of his feet and not lose his balance by keeping it all over the place. That’s one area that I’m helping him.

"Jacoby, Pat and Taylor are definitely the ones who have progressed the most, and they’re doing a heck of a job leading in terms of off the field, intangibles. We don’t really need to do a lot from a motivational standpoint. [Offensive line coach Ed] Warinner does all the work there, because he’s grinding them day in and day out.”

Warinner is probably the most important holdover for the linemen, though the rebuilding job almost became even more challenging with the highly respected assistant in the mix for head-coaching jobs again this winter. If more dominoes fall this offseason, he could still get back in the mix for a position elsewhere, which would really cloud up the crystal ball for the Buckeyes on the offensive line.

But at least for one more week, Ohio State knows exactly what it has.

“I know people talk a lot about us leaving and the shape of the offensive line, but I’m not worried,” Mewhort said. “I know there are a lot of hard workers in there and a lot of guys who are going to be very good players in the future.”

The chance to prove it is creeping up quickly.
