I like the cWPA metric better than WPA for the reasons you outlined, and it does a good job of quantifying the ‘clutch factor’ that so many statistics lack. My one concern would be that players that are playing on teams that are doing very well, like Harper’s Nationals and the Cubs, are getting penalized a bit for winning so many games. Is it right to say their games are less meaningful because they’re so far ahead? Being ten games ahead lowers the CLI of those games — in a way, it seems like this metric would most benefit the players on teams that consistently win ‘big’ games, but also consistently lose small CLI games which in the long run keeps them in a tight race. Don’t feel like that’s totally fair. Regardless, better than WPA alone in my opinion.
