Sage Mightygoose, if this hereby Court be pleased and this evident is current, I'm going to call it now in line with your recent prophecy on another thread.
But is this the current XFL view or something from weeks ago?
If and only if still current, here's my take.
Given that this XFL 3.0 has zero plans to intersect with the NFL at all, that means they are married to spring football just as I suspected from most of its fans. They also have the false assumption that by having any football in the fall, one has to take on the NFL, which is simply not tree so long as you don't schedule opposite the NFL!
Now if there is some deal done with the CFL at all to be had, which I am not seeing now either, it would have be analogous to as you proposed with a split season with the autumn the CFL only.
Something I have observed in life across industries goes kind of like this:
"When in the midst of challenging efforts to find a solution, when the only solutions are those that are extremely complex as opposed to in a mix with more streamlined solutions, the chance of the extremely complex solution being chosen is slim to none."
This view does not mean complex solutions ought not to be discussed for what is not a simple one-meeting one-hour conversation, for in such discussions come ideas for a simpler solution.
This view means rather that when such are the only solutions on the table that are viable given other parameters (i.e. the XFL will not intersect at all with the NFL season), those solutions are heavily unlikely.
CFL, much as I must do with my dating pool post-pandemic (or so we think given the alarming variants), please go fishing in a different lake right now.
