There has been chatter about this for a long time. Per the AD meeting its the fact that DA kids are allowed to play DA for Privates and not public. The last straw.
And yes, there are private schools that are not recruiting athletes or giving financial aid for sports. OL soccer is a prime example, but they could.
There has always been an uneven playing field with recruiting, unlimited boundaries, etc. Recruiting for athletic endeavors and athletic-based financial aid has increased a lot in the past decade, and what was reserved for football and basketball has leaked into many sports and per reports that may lead to a proposal to make the change. It's not unprecedented as there are several states that have gone down this path and it has worked for both groups.
