At this point, I still try and watch every Ranger game. That's generally impossible, but I'm still up around 75 regular season games and all the playoffs.
The Yankees are probably the next followed team, but it gets later and later into June by the time I start really following them, and now, MLB is getting harder and harder to watch and enjoy. I certainly don't watch as much as I did even 10 years ago. My daughter doesn't really like baseball outside of a few players, so even going down to Atlanta a few times a season to see a game live is out.
The Giants would be next, but I only watch the Giants. The NFL sickens me. Outside of the playoffs, I really don't care about the NFL. DirecTV gave me Sunday Ticket for free the last two seasons. I only watched the Giants. With the changes in broadcast partners, who knows what my options are for that, so the NFL may fall even farther behind.
I follow the Knicks casually. Pre-COVID we'd go to a Knicks-Hornets game here in Charlotte occasionally, but it's been years since we did that. I do enjoy when the NBA channel picks up a MSG broadcast, but not enough to buy the NBA package like I do with the NHL.
Honestly, my second favorite professional sports team now might be Liverpool FC.
