It's just that when people don't say 2019-20 (which eliminates all confusion) they say 2020. Not 2019. Not really semantics.The 2019-2020 season. Gaffney's freshman's season would start the fall 2019. Lets don't get hung up on semantics.
It can be confusing. The recruiting class for one year plays as freshmen class in the next year's season.
