teams I follow have been very mediocre the last 15 years or so. My teams - BYU football/basketball, Jazz, 49ers - all seemed to do well during the '80s and '90s. The only recent exception is the Seahawks (lived in Seattle from 1999-2016).
I will probably watch the Superbowl at least as long as it's close, but I have little enthusiasm for any sport. I will say that I have watched almost all of the BYU men's bb games this year and I enjoy this team though I don't have a lot of hope for the NCAA tournament.
