I guess it depends how you define biggest. I mean, the Superbowl happened obviously. If you mean unexpected at a major event, Andreescu winning Indian Wells probably tops it.
There's some interesting names in the negative WAR list in the early going. Blackmon (-0.6), Jose Ramirez (-0.4), Nolan Arenado (-0.2) really jump out. Somehow Billy Hamilton has put up negative defense too. Small sample sizes are fun!
Lol, Beverley and Durant just got a second set of technicals and thrown out of the game. This one is probably over anyway, but I'm thinking that's a tradeoff the Clippers are probably fine with.
