Teams know this and use it to get us to overspend with prospects. The actual catchers who hit free agency are all flawed in someway. It's better to have a above average defensive catcher than one who can't catch but hits .240 which is the current league average for batting.I still think they could have done a better job at replacing Sanchez.
The Yankees have lost a single digit amount of games so far this year. I'm pretty sure their offseason plan is working out just fine.
