I expect Men's sports will continue to grow as schools struggle to get men on campus. I expect we'll continue to see football being added as it is a driver of alumni donations and a marquee sport that makes a big splash, but it's also a very expensive startup. Men's volleyball, like adding women's lacrosse, is a pretty simple rescheduling of practices in an already available facility for a lot of schools.
Too a point... as long as Title IX is followed. The challenge with this is to get more men on campus is nice, but there is already women on campus and schools have to watch the numbers very carefully. Adding a massive numbers sport like football nearly always has to be countered by a women's sport of some size (i've seen ice hockey added as the alternative). So yes, to get more people like men on campus football is an option, but not without a lot of challenges.
Unfortunately, football is like wrestling when it comes to Title IX in the sense that there isn't an obvious counterweight. To add football, you have to find a completely different sport with decent numbers (those depend on the school) and now things get more complicated.
The sport that is actually the best to add and many are considering now-a-days is lacrosse. Sure, the northeast has plenty of lacrosse teams, but it is the fastest growing sport in the NCAA for good reason. You can get the same or at least similar numbers without the same costs and certainly with less safety concern. A school also might be able to add the sport at slightly less numbers to keep the big sport from having as big an impact on Title IX. And if it does have an impact, adding women's lacrosse is far easier than a completely different sport.
