I think most also look at taxes. State income taxed teams are at a disadvantage.
Saw an article from PFT that Ramsey contract at 18mil per year, each game played in California he gets taxed 133k per game.
It's zero in Florida.
I think Dallas still has that prestige but it comes down the dollar. If Dallas is offering 6mil, but you can get 8-9mil from another, off you go. Paydays only happen once or twice to a 100's of players, out of thousands. Paying state tax may be worth it if it still comes out ahead from Texas rates.
