My interest in sports as a whole has dwindled for years, ever since I hit my 30s. The quarantine has reinforced that. Too much other stuff going on in life. They're still my prime source of entertainment but I really don't miss them all that much. I'm still a huge Knicks and UConn fan but that's it. I used to be a four-season die hard. Loved MLB, NFL, NBA, CBB, CFB. I watched a fair amount of golf.
I stopped following MLB a decade ago after being a huge Yankee fan for 20 years. Stopped cold turkey one season; my interest died overnight and never came back. Interestingly, out of my group of high school friends (about ten of us) all but one of us stopped following MLB around 2010-2012. Not sure exactly what happened but something turned off all of us. Baseball chatter gets derided when it gets brought up in our group chat.
I'd barely follow the NFL if it weren't for fantasy football. Maybe watch part of the SNF game if it was an interesting matchup. I couldn't tell you the last time I watched a college football game. Football is too slow and too boring for me. Three-plus hours of TV and commercials for 11-12 minutes of action. I think RedZone and fantasy ruined my fanhood.
With UConn going to the AAC in 2013 it killed my interest in college hoops though hopefully that'll be revived now that we're back in the BE. I used to watch several non-UConn games each week (Big Monday, Super Tuesday, etc). I haven't watched a non-UConn, non-tournament college basketball since probably 2012 or 2013.
I still love the NBA. My interest there hasn't waivered recently (it did in a major way from '00 to about '07--the league was awful) but it's been strong the last 13 years.
I'm going strong now without sports but I will admit that winter will be really tough if there's no basketball. Hunkered down through a New England winter with no hoops would be a drag. I'd be reading two books a week (probably a good thing) if we don't have basketball.
