The dominoes, ultimately, only fall once.
We lack the power to turn back time and rewrite history. So all we are left with are the abilities to wonder and speculate about how things might have turned out had different decisions been made, how one fallen domino might have led to the next.
But that doesn't stop us. In fact, the inability to change history only deepens our desire to re-imagine it, for better or worse.
Star Tribune Vikings beat writer Ben Goessling and I played a version of that what-if game on Friday's Daily Delivery podcast.
The upshot, which we arrived at in meandering fashion, was this: Would Kirk Cousins still be the quarterback of the Vikings this season if Minnesota had hired Ryan Poles as its general manager?
The question is particularly relevant as the Vikings prepare on Sunday to host the Bears — the organization that did hire Poles as GM, with the Vikings opting to hire Kwesi Adofo-Mensah.
In Chicago, Poles has orchestrated a more thorough roster reconstruction than Adofo-Mensah has authored in Minnesota.
The Vikings labeled their effort a "competitive rebuild" and opted to keep a lot of their core intact. The biggest piece of that was giving quarterback Kirk Cousins a one-year extension through 2023. It is paying off so far, with Minnesota sitting at 3-1 — one of the eight NFL teams that currently has a winning record.
