I can't really speak for any of them on what their actual reasons were, but I'm pretty sure Kynard transferred because of the incoming class of Freshmen and two transfers. She wasn't seeing as much playing time as I imagine she expected to see and then with what would of been 7 players vying for the guard position, probably wanted to be more of a contributor. Honeycutt wasn't getting a lot of playing time for Foster and maybe didn't see herself fitting in with McGuff's program. She didn't play a single game for McGuff, transferring after the second game of the season which she was not in attendance and had a headache for the opener. Ferguson didn't just transfer but was asked to leave the team after breaking team rules for the second time.
The Freshmen class was just 5 players, still pretty large, but that's because Coach Foster wasn't able to recruit any players in his final season, which I'm assuming that's what you are referring to when you say "the had (to start with)". Cooper will be considered a Sophomore this year. Holland will be a Freshmen again. They do not have any seniors on this team so whatever amount of players Ohio State ends with this season will be the amount plus 2, hopefully 3, for next year. Still what was looking to be an exciting year for Ohio State seems to be tapering.
