MPSF doesn't have Tennis. It'd only be WAC schools, so why bother? They can just play an 8 game double round robin schedule, or play more regional tourneys. There are other options, as many conferences are light on schools, especially the men's side. Most likely the schools will scatter and find homes, or if they were only sponsoring the sport to support the WAC in the first place they'll drop it.

For the record, I put a UMKC move as a 3 on a scale of 10 for likelihood of happening. It would be a 1 or a 2 in most conferences, but this is the WAC. That just means it's worth keeping an eye on, but until something a lot more solid is out there, it's just chatter.
