Yes, football used to be the only sport I watched. I followed the 49ers and Stanford, where I taught part-time. But I (and my friends) began to feel guilty about players sacrificing their health for our entertainment. So I backed away somewhat. But I confess following the 49ers last year.
Favorite players (current): Jimmy Garoppolo, George Kittle, Arik Armstead, Nick Bosa, and Christian McCaffrey (who went from Stanford to the Panthers).
Favorites (retired) Jerry Rice, Joe Montana, Steve Young. I could name many more greats, but these are the players that I often watched. I've briefly met Montana and also Y.A. Tittle.
