PSLs will probably net somewhere between 50-100 million. It's not nothing, but it's not covering the Pegulas share. The 200$ million from the NFL is also a loan that the Pegulas need to pay back (I think I read it's supposed to come from away team ticket sales over the length of the deal.)
With all that said, I still very much wish ownership paid a bigger share and that NYS / Erie County (and taxpayers) paid less.
