I'd go to jai alai, if I lived in Florida, esp. Miami, might watch the SB, and NBA finals, maybe the WS, too.
Betting is huge in American sports. I wouldn't watch one second of NFL without a bet. I never know what just happened, shit is called back with flags and penalties, every play. I wouldn't even want to attend an NFL game, NBA....I want Jack Niclausson's seat in LA, then I'll go, preferably with J-Lo sitting on my lap, to make it bearable.
MLB is real, minor league is the best, I like AAA, don't even have that in CT, 50 miles drive for AA baseball.
Jai alai is the best sport, of all.
