The WNIT has 64 teams, unlike the 32 in the NIT. So the WNIT issues an automatic bid to each conference. The automatic bid goes to the team in each conference highest in the standings, that's not in the NCAA Tournament. So now that I look at it, it's not 100% guaranteed, but pretty close.

If JMU wins the CAA, Drexel automatically goes to the WNIT, unless they get an NCAA at-large bid. If Drexel wins the CAA, JMU probably gets an NCAA at-large bid, so Hofstra would get the automatic bid to the WNIT. If a team other than Drexel or JMU wins the CAA, JMU would still likely be in the NCAA Tournament, so Drexel would likely get the WNIT automatic bid.

Point is that the CAA is guaranteed to have at least one team in the WNIT, and with Drexel finishing 2nd, it's very likely that they would get that automatic bid.
