Did 3 games/matches when I was there.
Basketball (Lakers) - Pretty terrible tbh, I wish this was hyperbole but by far the loudest the crowd all night got was when the score met whatever the criteria was to get some 99 cent tacos for free
Baseball (LA Dodgers) - Sport is not exactly exciting but found the experience as a whole pretty enjoyable
Hockey (San Jose Sharks) - Was really disappointed in this, thought that the game and the crowd would be the closest experience to football, but it was just flat. In fairness, the team had already qualified for the play offs so it was a bit of a dead rubber and may not have been a good representation.
Also had a tour of AT&T stadium, and an unofficial nosey round Oakland Colosseum, and to be honest I enjoyed both of those more than the matches we went to.
