Soccer is growing and growing. Baseball is dying.
If soccer is glorified jogging, baseball is glorified standing and spitting. (BTW I grew up loving baseball and will be venturing to Baltimore in 2 weeks to watch my Orioles, who I still follow.)
You probably are not aware of how big youth soccer is in the area. Far more kids play it than play baseball. Many play year round.
In case you didn't know, the student body and locals fill the stadium to overflow. The place can get pretty loud. There have been discussions of a bigger stadium and a grass pitch.
The men's team puts guys into the MLS on a consistent basis . One guy is a starter on the USMNT.
A baseball team would be a cellar dweller on a regular basis. No southern/western kid would want to come play in the rain and freezing cold when they have other offers.
Few students would go to watch baseball. Also, where would they play? I doubt the Mets would lease the field.
Lastly, that's only 9 scholarships freed up. Fully funded baseball is 11.7 scholarships. I assume that the ACC requires all sports to be fully funded. Also, the ACC would probably have to agree.
