I've probably said this here before, but there was a period 2010-2014 that was insane for sports fandom in my house. The SF Giants won three world series, the Badgers played in three Rose Bowls (earning two of them with conference championships), Notre Dame played for a national championship (while that ended in a thud, the season to get them there was a lot of fun), the Packers (my NFL team) won a Super Bowl with one of the greatest QBs of all time, and the 49ers (the local team) played in a Super Bowl and became good again under Jim Harbaugh, after several futile years. Even the Sharks were really good, though they never could quite seal the dal. It was a good time to be a sports fan in my house. And since then there have been a lot of good years, too, including with the Warriors becoming one of the dominant teams.
I tried to explain to my kids that this is not what sports fandom is really like. Typical is losing the one game you need to make the bowl game you were hoping for; missing the playoffs, or the next round in painful fashion; watching other teams stockpile talent and wondering why your team can't do the same; having a brilliant first half against a long time rival/thorn in your side, only to watch their superior talent overcome the solid fundamentals that your team relied on to get you there. Etc., etc., etc... (fortunately I'm not really a Brewers fan--I just hate the Dodgers--but that last example sure played out during the NLCS last week).
