It was an extremely poorly constructed roster. Jones 4* transferred after 2 games and D Davis got hurt at the start of the B10 season. Other than that it was Rob Johnson and freshman Justin Smith. That Ohio State roster had 4 top 100 players in their starting 5 including 4 upperclassmen and Kaleb Wesson who was freshman all-B10. Roster doesn't compare to Ohio State's in all honesty. KBD was a former 5* player who was injured the year before and went on to win B10 POY. Tate, CJ Jackson, and Kam Williams were all multi-year starters as well.
That was indeed a poorly constructed roster and deceives a lot of people who comment.
Unfortunately, four years later it is still a poorly constructed roster.
