Collision Sport

Normally I am in agreement that the rules of baseball are historically pretty solid...and as technology has improved (or even been invented) it should be used to correct the failed calls in the game...or justify what was called...a red flag or something would be OK...or even, somebody up stairs calling down to review a play...it's not like the game is break neck speed...
However, there is a play that must be eliminated...the collision of the runner and the unprotected catcher, bracing himself with the impending doom...it's near a criminal act that needs to be abolished...hey, I know a bunch of your purists who say that it should remain...I say get your fat ass down there and YOU take the hit then...GET RID OF IT!
The play that has ruined SF's catcher, Buster Posey, is just another example of such an example...
