I don't think Cousins was trying to injure Posey, but I definitely think he made up his mind to blow him up as soon as it was apparent there was going to be a play. I just don't that's appropriate. And the way he hit him was excessive, even if the catcher had the plate blocked, which he didn't. So if he hadn't tried quite as hard to knock the ball loose, that would have been okay? Cousins is running full speed down the line and the only thing he can likely see clearly before he has to decide what he's going to do is that the throw beat him by a mile. Unless he knocks the ball loose or Posey kicks it, he's out. So he used his only option, and it turned out horribly because not only was Posey hurt, he didn't field it cleanly which meant the contact seems unnecessary. That said, Cousins shouldn't have that option available to him. We don't let guys stretching singles into doubles blow up middle infielders before getting a hand on the base, and the same should apply at the plate. However, if you go down that road you have to protect the runner's rights by aggressively calling interference on catchers who try to obstruct runners without the ball. I'm starting to lean this way. I know people love the collisions at the plate, but it's just too dangerous. Many times the catchers aren't even looking and their padding does very little to absorb any of the damage. I'm all for changing the rules on blocking the plate if it keeps catchers from getting absolutely blown up at the discretion of the runner.
