When a team has as much turnover as Ohio State basketball experienced this off-season, there are bound to be a few major question marks hanging above the season.

Combine that roster turnover with a global pandemic, pushed-back start date, and drastically changed schedule, and the result is a recipe for the unknown.

Entering season No. 4 at Ohio State, Chris Holtmann has slowly constructed a roster that fits his style-- in large part through the transfer market. The influx of new talent entering Columbus is what makes this season so hard to predict.

We’re already nearing three weeks out from Ohio State's season-opener, whenever that may be. Schedule mayhem aside, let's attempt to answer three key questions about this Ohio State roster.

This is the big one. Wesson was not just Ohio State’s leading scorer last season. He directed traffic on offense, had his own gravity in the post, was a top-notch three-point shooter, and anchored the paint on defense.

Replacing the big man will be easier said than done.

Harvard transfer Seth Towns is a high-level scorer, but Holtmann has stated that Towns most likely will not be ready to play full-contact basketball come late November. The 2018 Ivy League Player of the Year is recovering from a series of leg injuries that have held him out for two years.

Ohio State may take a committee-based approach for matching everything Wesson provided. Between Towns (16 points per game in 2017-18), Sueing (14.3 points per game in 2018-19), and junior guard Duane Washington (Ohio State’s second-leading scorer last season), there will be more than enough scoring punch to make up for Wesson’s 14 points per contest last season.

It’s every other area that will provide a challenge. Wesson pulled down 9.3 rebounds per game as a junior and commanded the interior. E.J. Liddell and Kyle Young can match his output on the boards, but neither has the size or post skill to control the offense. One of the two starting big men will have to become an outside threat to spread the floor for the athletic wings on the roster.

Under Holtmann, Ohio State has played slow, and rightfully so. In his first season sans-Wesson, that outlook may have to change. There are plenty of skilled guards and wings on the roster, and without a go-to post threat like the big man was, the best way to stay competitive on offense is to utilize the athleticism of this roster.

Replacing a player with Wesson’s impact across the board is nearly impossible. The key for transitioning to a post-Wesson era will be adapting to the new strengths this team provides. There is more than enough talent to make up for his stats, but replacing his presence on the court will be a work in progress throughout this season.

The starting big men for Ohio State have been set for months now. The promising sophomore Liddell owns one spot and experienced senior Young will man the middle. Both are talented and have shown plenty of ability to hold their own inside, but both are also significantly undersized.

Ideally, Holtmann can find a third big to rely on when one of his horses needs a rest. Last season, that energy off the bench came from Liddell, who stepped up in a major way in late Big Ten play.

Entering this year, there appear to be two main options for key bench minutes down low: 6-foot-10 sophomore Ibrahima Diallo and 6-foot-8 freshman Zed Key.

Diallo appeared sparingly last season, playing in just eight games for a total of 40 minutes. The Senegal native is long but very thin and was extremely raw on the court as a freshman.

With a full year of college and off-season under his belt, Diallo has the potential to make a major leap and become an asset for a fun-sized Ohio State team in 2020-21. Time will tell, but Holtmann has stressed patience when it comes to the second-year center.

On the flip side, the Buckeyes' head coach has raved about Key, a four-star recruit from Long Island.

“Zed has been –– as we’d expected –– he’s physical, he’s 6-8, 7-1 wingspan, about 255 pounds. He’s used a lot of that 255 pounds in our workouts,” Holtmann said. “He’s a strong, strong kid.”

Key already has the body of an experienced high-major player. His size and strength give him an advantage over where Diallo was as a freshman. Key may be able to battle in Big Ten play from the jump, a rare trait for a first-year player in the conference.

Inevitably, Key will experience the freshman woes that most do under Holtmann-- Liddell went through a similar stretch last season and blossomed late. If Key can replicate that growth, he has a chance to become an important contributor for an Ohio State team that needs interior strength.

No matter which one of the big men steps up, it’s critical that bench production from the forward spot exists. Young has struggled with leg injuries throughout his career and Liddell is still growing as a player.

Depth on the inside is critical, especially in a physical conference like the Big Ten.

With the unfortunate loss of Utah State transfer Abel Porter for the season on Wednesday, Ohio State appears to have slim options at backup point guard behind senior C.J. Walker.

Though Walker (8.7 points, 3.5 assists per game as a junior) will run the show for the vast majority of available minutes, having a backup guard to lean on who knows the offense and can control tempo is important in Holtmann's system.

Bucknell senior transfer Jimmy Sotos had his waiver approved by the NCAA on Thursday. He averaged 11.5 points and just under four assists per game as a full-time starter for Bucknell, showing good shooting touch and impressive skill in the back court.

Sotos appears to be the main option at backup lead guard entering the season, but as an immediately eligible transfer, he has not had as much time to fully learn Ohio State's offensive and defensive schemes.

Walker, a transfer from Florida State two seasons ago, was able to sit out a year and develop himself into the starting point guard for Holtmann. Sotos will not have that luxury, and if he isn't able to fully adapt to the system (coming from a much smaller school and conference than Walker), the remaining options are slim.

Both Sueing and Washington have the skills to play emergency lead guard, but both are score-first players with high turnover rates. When freshman D.J. Carton left the program last season, Washington was able to step up as a secondary ball-handler, but there is still a clear scoring role the junior needs to fill.

Freshman Eugene Brown III showed some ability to lead an offense in high school, but he's a freshman. Holtmann has cited the need for Brown to improve on the offensive end, and first-year decision-making is never something to count on.

On an overall level, this isn't a massive concern for Holtmann's team, but the loss of Porter presents some rotational challenges. Washington has proven his competence in controlling the offense and Sueing has the potential to work as a point-forward. If Sotos steps in confidently, the concern over a lack of point guard options evaporates quickly.

We’ll find out how a new-look Ohio State team answers every question it faces when it takes the court in late November.

It will be a fascinating season for the basketball Buckeyes.
