I have been very fortunate to go to a ton of games in my life. I've been to 4 different World Series' starting in 1989. I went to multiple NFCCGs, including a classic Cowboys vs. 49ers game. I went to an NBA Finals game in 2015. I saw Barry hit #73 and #756. Matt Cain perfect game. Tons of other playoff games.
With that being said, there is absolutely NOTHING that compares to games 3 and 4 of the Mavericks playoff sereis in 2007. Nothing comes close to those games for me, and I doubt anything ever will. Such an unreal experience. Game 3, I would estimate 90% of the crowd was in their seats an hour before tipoff, chanting Warriors. It was such an incredible experience...one I wouldnt have traded for the world.
(This wasnt supposed to be a humble brag or anything. Just pointing out how special those two games were as far as game day experience.
