Good questions, and the answer is "We'll find out." No way to really predict all the ramifications of losing the 2020-21 sports seasons. But I would guess that there will be kids who decide to drop soccer entirely, some opt for upgrading their school/soccer program, maybe slightly fewer opportunities for new incoming freshmen for the next season as the number of 5th year seniors/grad student players increases.
I predict that the much bigger impact of this pandemic is not going to come from the loss of the next season, but from the budget crisis that is going to sweep the entire college landscape starting now and over the next several years. Schools formerly in decent financial condition are going to tighten their belts, schools just getting by are going to have to slash massive amounts of money to stay afloat, and those that were already having trouble are going to shut down entirely. I can guarantee that is going to hit soccer programs (men's and women's) across the country, and there will be FAR fewer opportunities for scholarships and roster spots in the coming years. Already, my player's college coaches are talking about losing support staff and resources as part of budget cuts, and her school's women's soccer program is the premier sport at her particular school (DII).
I really, really hope I'm wrong.
