Somewhat off-topic, because I truly don't believe Barkov is going to base his signing decision primarily on whether he wants to keep living in Florida, but...
I've known/met a lot of young people ages 21-35 who grew up in Florida. I've yet to meet one who speaks particularly highly of it. I think Florida is a great state to go to college in, and obviously retire in, but I'm not aware of a big post-college youth movement happening in that direction.
Barkov clearly has enough money to live in the absolute nicest part of whatever city he chooses to play for. He has the money to travel to whatever beach vacations his heart desires, whenever he wants.
This idea that Florida is the most ideal destination in the US for professional athletes gets brought up a lot here, but the results just don't really seem to back it up. In any sport.
Lebron, Wade and Bosh teamed up in Miami cause of the cap space and opportunity. Not because they were all obsessed with Florida. Where are the examples of huge athletes who weren't drafted by Florida teams deciding to play for Florida teams?
