Yep. The article, ensuing speculation, this thread, all based on an incorrect reading of a financial filing.
A quick scan on Edgar (Sec) would get you the details of the security interest from Kevin Glazer's previous filings (2017).
The fact that all 6 Glazers needed to take on individual loans on the day they removed their shares from Red football LLC does hint at a refinancing of a loan that resided in that company. Only K Glazer has signaled that his B shares are no longer being used as collateral.
