It has always been a truism that Catchers get hurt more. I’m not sure this Roto Think Tank story about a Eugene Freed study goes very far to prove anything. But it does suggest that the opposite is true.
More math needs to be done over more seasons to be convincing, but the better argument (I think) is that catchers get hurt in fits and starts. Relying on a costly catcher may increase your risk, but getting real production from a dead position has its own rewards. The strategy changes if you’re trying to win one year, or every year.
