How far do we need to delve in? Were those players added because McDaniel is a better communicator than Flores? Did he have a better relationship with the front office than Flores? Did they spend FA money on Kyle Van Noy, Byron Jones, Shaq Lawson, and Emmanuel Ogbah instead of offensive skill pieces at Flores request?
If GM incompetence is the excuse, you could make a lot of the same arguments for Kliff. Bad roster, same as Kliff. Dinged up young QB, same as Kliff. Owner issue, same for Kliff. In the end, both dudes weren't able to get the job done. I think Flores could be an ok coach but all of the things he couldn't overcome in Miami are pretty much present in Arizona. What makes me believe he can overcome them now?
