What do you think? there are very rarely catchers with high WAR numbers.
I think the biggest problem is the adjustment for playing time. of course it is good that a player who plays more games has a higher WAR (you can only help your team if you play).
however you can't play every day as a catcher. one off day per week is absolutely normal. I would consider 140 games for a catcher equal to 162 for an infielder.
I think it would be better if WAR would consider this just like WAR doesn't punish starting pitchers for only pitching every 5 days.
To me because of this catchers are very underrated by WAR. A SS will receive the same positional adjustment but unlike the catcher he can easily play 160 games. that means a catcher can never reach the same WAR unless he really hits A LOT better.
So why not normalize a catchers season to 140 games?
