OSU won, 52-24.Credit: Mark Batke / Photo editorWith all the success the Ohio State offense has had in recent weeks, there is one spot where the Buckeyes aren’t up to par: the red zone.Coach Urban Meyer said his team’s play inside the opponent’s 20-yard line simply isn’t on track with the expectations at OSU.“It’s not very good at all,” Meyer said Monday. “For what we expect, it’s not good.”Overall this season, the Buckeyes have put points on the scoreboard 23 times in 28 trips to the red zone, coming out to a conversion rate of just 82 percent. Of those 23 scores, just 19 have been touchdowns. Those numbers compare to a 92 percent success rate for opponents, who have scored 10 touchdowns and added one field goal in 12 red zone tries against OSU this season.In 2013, the Buckeyes scored 60 times in 63 attempts — a 95 percent success rate — including 53 touchdowns in the red zone. That means the 2014 Buckeyes are putting points on the board in the red zone less often than last year’s counterparts were able to come away with touchdowns alone. Their opponents, meanwhile, were held to a 79 percent rate of success inside the 20 last season.OSU’s success rate was just over 71 percent in its most recent game — a 52-24 win against Maryland on Oct. 4 — as it went just five for seven in the red zone.Meyer said the success — or lack thereof — near the goal line comes down to coaching and not the ability of the players on the field.“It’s not the players’ fault, it’s our fault,” Meyer said. “It’s coaching errors, whether it be tempo, we just have to do a better job.”OSU co-offensive coordinator and quarterbacks coach Tom Herman said he agreed the team’s red zone offense isn’t rolling at the necessary level, but noted the expectations are high when it comes to putting the ball in the end zone in Columbus, especially considering the success the Buckeyes have had since he and Meyer arrived in 2012.“I think our red zone, goal line or scoring touchdowns in the red zone is certainly not where we want it to be,” Herman said Monday. “Now we’ve set the bar pretty high finishing first in the country, I think second in our first year, first last year in touchdown percentage in the red zone.”The Buckeyes’ struggles in the red zone have them ranked all the way down at No. 72 in the country for red zone scoring percentage and No. 42 in the nation in red zone touchdown percentage. OSU was ranked in the top five for both scoring and touchdown percentage last year and 16th and second, respectively, in 2012.Senior wide receiver Evan Spencer said he has noticed the Buckeyes’ less-than-expected success in the red zone so far this season.“On offense, we’ve got to try to make sure that we’re capitalizing in the red zone,” Spencer said Monday. “We had a few times — last week I’m not sure, but I know the week before — we had a few times we got stalled in the end zone. Granted we’re putting up a lot of points at the same time, but there’s little small things that we can do personally and as a team.”Herman said one of the problems OSU has had near the goal line this season is making sure it takes advantage of soft spots in the opposing defense.“We don’t care what those weaknesses are,” Herman said. “We just need (to do) a better job of exploiting those weaknesses and not trying to beat our head against the wall into their strengths.”As players and the coaching staff have taken notice of the need to convert more often inside the 20, there has been more of an emphasis on it in practice — especially during OSU’s recent bye week.Senior tight end Jeff Heuerman said the coaching staff focused on red zone offense more often than normal last week after the less-than-stellar showing against the Terrapins.“We obviously had three days of practice, I think we did red zone two of the three,” Heuerman said Monday. “We usually only do red zone once a week.”He said the Buckeyes also practiced “some live short yardage situations” that they wouldn’t normally.Herman said improvement on that part of OSU’s game will be key going forward, and added he believes it can happen if the Buckeyes continue to work toward executing every play throughout the game.“I think we’re capable now and moving in the direction of, ‘Hey, you need to play with great technique for 80 plays in a row,’” Herman said. “And I think that’s a fair expectation given the point in the season that we’re at.”The Buckeyes are scheduled to return to the field Saturday against Rutgers at Ohio Stadium. Kickoff is set for 3:30 p.m.
