COLUMBUS, Ohio - Ohio State will have a historic draft class this season with Chase Young, Jeff Okudah and J.K. Dobbins among the many Buckeyes that will highlight the NFL Draft in April.

It's a testament to Ohio State and its coaches that so many players will be high draft picks, but with that comes the impact on next year's team.

Ryan Day and company will have to figure out how to replace the departing Buckeyes who contributed so much to the team that got all the way to the College Football Playoffs.

We know that Ohio State will be losing many juniors and seniors that were leaders in the locker room and dominant on the field, but what about the numbers? We're taking a statistical dive into how much the Buckeyes are losing from those moving on from college football.

The biggest loss will be felt immediately in the rushing yards that J.K. Dobbins will be taking to the NFL with him.

Of Ohio State's 3,770 rushing yards last season, Dobbins accounted for 2,003 of them, or 53 percent. The last Ohio State running back to make up that much offense on the ground was Ezekiel Elliot back in 2015 when he accounted for 56 percent of the team's rushing yards.

Dobbins also scored 21 rushing touchdowns and added two receiving touchdowns, accounting for over 25 percent of Ohio State's 87 touchdowns on offense.

With Master Teague III sidelined with an injury for the foreseeable future, it isn't quite clear where these yards will come from as Day and Tony Alford may opt for a running back by committee scenario, but it certainly won't be easy to replace one of the most productive running backs in Ohio State history.

Fortunately for Ohio State, they will be in the relatively unusual scenario this year in which there won't be a quarterback battle heading into the season, so Fields is sure to bring his numbers back as the starter for the Buckeyes.

As for the guys Fields will be throwing to, Chris Olave will return as Ohio State's leading receiver in yards, but K.J. Hill will leave with his team-leading 57 receptions in 2019.

Along with Hill, Binjimen Victor and Austin Mack made a significant impact for Ohio State, combining for 934 yards, 62 receptions and nine receiving touchdowns. This means the outgoing players will have accounted for at least 40 percent of the receiving yards, receptions and receiving touchdowns in 2019.

Though it won't be an easy task, the return of Olave and Garrett Wilson along with the incoming freshman class gives Ohio State more depth than they'll know what to do with, so finding playmakers to make up those receiving yards shouldn't be an issue.

Overall, the Buckeyes will be looking to replace a lot of production from 2019. The four aforementioned departing players were involved on over 50 percent of Ohio State's 7,454 yards from scrimmage last season, so players will have to step up to keep the Buckeyes' offense rolling like it did in 2019.

While the offense was lights out in 2019, what may have been more shocking was the defensive turnaround last season that helped lead the Buckeyes to their first College Football Playoff appearance since 2016.

The headline of the defense is none other than Chase Young, the phenom defensive end who led the nation and set an Ohio State single season record with 16.5 sacks. This was more than 13 FBS teams had during the entire season.

While the two-game suspension may have hurt Young's number when it came to a potential Heisman candidacy, it was still undoubtedly one of the greatest defensive seasons in Ohio State history.

It won't be easy to make up those sacks next year, but the return of Jonathan Cooper along with Zach Harrison, Tyreke Smth, Tyler Friday and Javontae Jean-Baptiste should help numb the pain.

Moving inside, the biggest lost will be DaVon Hamilton. He led the interior with six sacks and 9.5 tackles for loss. Jashon Cornell and Robert Landers also combined for 22 tackles (14 for loss) and 4.5 sacks, and it will be up to the likes of Tommy Togiai, Antuwuan Jackson and Haskell Garrett to make up some of the losses inside.

Across the middle, Malik Harrison led Ohio State with 75 tackles and was second on the team with 16.5 tackles for loss. While his presence will be missed, the Buckeyes will be in good hands with two seniors (Pete Werner and Baron Browning) and a graduate student (Tuf Borland) prepared to fill in.

Moving back to the secondary, Ohio State will be losing three starters in Jeff Okudah, Damon Arnette and Jordan Fuller.

It can be more difficult to track lost production in the secondary as the best players like an Okudah or Arnette may not be thrown at as often or can cause an incompletion that may not be credited to them.

Even with the possibility that the stats sheet doesn't reflect what they brought to the team, the numbers still show an impressive 2019 campaign for the Ohio State secondary.

Fuller was third on the team with 62 tackles and had the most tackles among non-linebackers. Okudah led Ohio State with three interceptions while Arnette took back the Buckeyes only pick-six of the season against Indiana.

Overall, departing players accounted for over 45 percent of the team's 825 tackles in 2019. Additionally, the Buckeyes will lose 52 percent of their tackles for loss (66 of 126) and 10 of their 14 forced fumbles.

It's a challenge every season to figure out how a team will make up lost production from players.

Does it involve incorporating more freshman like Ohio State may do at the wide receiver position, or does the pressure shift to the juniors and seniors that have waited their turns to start like those who will look to replace Young and Hamilton on the defensive line?

There isn't an easy answer, and with spring practice cancelled, it will be a while before its clear who might step up for Ohio State in 2020.

Rest assured, however, knowing that the players who stood by while watching Chase Young and K.J. Hill dominate college football understand the expectation that has been set for them in their future with the Buckeyes.
