Lots of teams have shaky hitters 6 through 9. But, yeah, they do need to upgrade at catcher assuming Kieboom doesn't keep improving.
The good teams less so.
If they sign Corbin and Harper they can’t afford Grandal or Ramos. The other free agents are not anyone you want.
I doubt they can sign both guys. Wouldn’t mind them signing Matt Harvey. Looks like he has learned how to pitch at reduced velocity.
Has Ross learned a third pitch he actually uses? If not why does anyone think he can start?
