Or, $2.66MM over a 4 year contract.
It's significant. Definitely factor worthy. Plus, you consider cost of living difference beyond just taxes accounts for a standard of living reduction of approximately half between LA and somewhere like Jacksonville and a person making that salary in LA lives like a person making close to $11MM per year comparatively in Jax.
I'm not in that bracket myself, unfortunately
, but I can speak as a person with actual experience in making the decision between SoCal and a couple other places in the country making roughly the same annual income and the taxes and standard/cost of living difference were a significant factor that kept me away from a return to my home state. No fiscally conscious person is going to simply overlook it, even at that income level. Especially those in a job as insecure and short lived as NFL head coach.
