New feature: Statistical Feats
Available now, view all the great performances in your league on one page. Just go to Stats > Statistical Feats. Triple doubles, 5x5s, 50 point games, etc. Eventually you will see this information pop up on player pages, team history pages, league history pages, and more. But for now, it's just on the Statistical Feats page, all in one place.
Note that this will only track performances from now on. It won't go back through the history of your existing leagues.
