Ohio State's most depleted unit is its offensive line.

After the O-line anchoring the team for two straight years, Urban Meyer must find replacements for four senior starters. The lone returner—Taylor Decker—has flipped from right tackle to the left side in order to protect Braxton Miller's blind side.

Only one of the four vacancies was filled during spring practice. Pat Elflein secured the right guard spot, much like he did late last season when he filled in for the suspended Marcus Hall.

That leaves the left guard, center and right tackle positions.

At left guard, Antonio Underwood and Joel Hale are battling. Underwood is coming off a torn ACL, but his strong play didn't reflect that this spring. Hale is adjusting to life on offense after flipping from the defensive line, but his incredible strength is an added bonus on the interior of the line.

While Hale is surging, it's safe to bet on Underwood closing out the competition.

The center position featured two candidates this spring in Jacoby Boren and Billy Price, both of whom showed they have what it takes to anchor Ohio State's offensive line. Neither, unfortunately, will get the opportunity to do so. Alabama transfer Chad Lindsay, who will be eligible to play this season, will come in and win the job this fall.

Darryl Baldwin is in a great position to lock down the right tackle spot.
