Again, the investor analogy assumes that the investor is rational, a good judge of the "market," and able to account for his own emotional biases when making business decisions. Nothing about how the Wetenhalls operate leads me to believe that they fit the above criteria. In particular, Wetenhall the elder strikes me as irrational, out of touch with the "market" (i.e. clinging on to what worked for the team 10 years ago when things have changed league-wide), and too emotionally enmeshed to see things clearly. From his relationship to Popp (treated like the "extra son" in the Wetenhall family) to his idiosyncratic hiring practices (hiring Higgins because he reminded W of Trestman, which may play into Chapdelaine being hired into the same position) to his inability to see past personal friendships (being OK with a completely inexperienced Anthony Calvillo running the offense without any proper supervision), Bob Wetenhall does not, in 2016, strike me as a savvy investor at all. Which is why I am terribly afraid that he will opt for safe/status quo even though we can all agree that doing so works against his financial interests.
I don't have any evidence to support what I'm about to say, but I'm convinced that Wetenhall hired Dan Hawkins based on two things: Hawkins's "good old Southern boy" persona that reminded him of Jim Popp, and Hawkins's brashness, which probably reminded Wetenhall of Don Matthews. The problem is that you can resemble anyone, even a great coach, without actually being great. Hawkins had the brashness but none of Matthews's football IQ. And so he was a disaster.
But what did Wetenhall do then? He hired a head coach (Higgins), without doing any due diligence, a guy with poor credentials, who'd been out of football for years but who reminded him of Marc Trestman. And again, it was a disaster.
Then he went back to his crutch, his extra son, Jim Popp, for the 2016 season. Instead of breaking out of the unhealthy cycle of resemblance and comfort, he essentially turned the team over to someone who was not a competent head coach, based on the blind and mistaken belief that Popp could keep the team running for a year or two until Anthony Calvillo, another old friend who lacked qualifications, could step into the role. And for a third time, it has been a disaster.
Now, with Chapdelaine, I get the bad feeling that Wetenhall is, once again, relying on gut and intuition to give priority to a candidate, without exploring his options, because that candidate reminds him of Marc Trestman.
If you keep looking for an ex-spouse in the person you're currently with, you will just delude yourself and the relationship won't end well.
