football and tennis are the mains at the moment, NBA and F1 are the good faithfuls. athletics comes in dribs and drabs, a lot of others depend on the season
I'm a baseball fan. I've loved the sport since I was little. I was on a team in my home state for many years. I wanted to be a professional, but unfortunately, I didn't have the skills to do so.
Sports I enjoy are being ruined by technology in particular rugby, too many yellow and red cards and in football many great goals are ruined by silly offsides by toes and heels etc.
Too much linesman interference in rugby also.
MMA and Formula 1 are great to watch.
