I spent a bunch of time responding to comments but they passed me up while working on a well thought out reply, so I'm going to leave this as a generic comment...
My take:
Giants had already decided on Daboll, perhaps before any interviews took place. I am not a fan of Daboll, I think Flores is a SIGNIFICANTLY better coach here. I don't think any of this is simple though; There appears to be a problem with firing black coaches with winning records, i.e. Tony Dungy, Lovie Smith, Jim Caldwell, etc... However, the idea of "systemic racism" is a very complex equation where much of the accused racism can fall into a judgment call gray area. The problem then becomes deciphering what is actually "systemic racism" or what is actually people acting in what is natural interest in friends & families. With that being said, it is actually in the business' best interest to find the most highly qualified candidates, despite the NFL acting in the contrary, IMO. There are so many variables that go into this, I wrote a huge paragraph about it but then deleted it because I don't feel like responding to all the comments that it would get. The question then becomes, who gets to judge these decisions? On what basis? What recourse is there parties that feel slighted? What happens to parties that feel slighted but are incorrect? I think it's a delicate and very complex matter that I can't simply explain, and anyone who thinks there is a simple solution I would probably dismiss as not having carefully thought through the problem. (Not that anyone here is). This problem is not exclusive to the NFL, either.
The Rooney Rule will inherently cause some sham interviews. Perhaps revise the rule so minority candidates must be interviewed first to avoid what just happened? This won't change the actual outcome, however, this is simply just a more polite "F you". This really comes down to a fundamental human problem where the decision was already made, perhaps by the owner or others, then the interviews happened. At a human level, we do often make decisions without REALLY considering the alternatives, or we make decisions based on biases that we think are objective decisions. Solving this problem isn't so simple, but revising the rule would cool tempers probably.
Ultimately, I think this is one of the more egregious cases with Flores, but I don't think he will win this case going against a billion dollar industry backed by billionaires. I hate the Daboll hire, and I hate the Doug Pederson hire, both of whom are significantly worse hires than Flores.
