This is actually a pretty accurate breakdown. There are a few avenues to lower the hit next year he didn't explore (i.e. signing Gilmore long term), but it does illustrate some of the issues we'll face in the near future. More importantly, it illustrates these issues are, in fact, real -- and they won't go away by pretending Pegula has some mythical accounting powers that the other 30 billionaire owners in the league don't possess.
The most glaring problem to me is that while we will be fighting to stay under the cap in the upcoming years, these figures don't allocate any future spending for anything more than a stopgap QB.
