A subcommittee? They have those already and they have long recommended that this part of the game not change. EVERY player's union member has a vote already. EVERY means that they include all position players - even the ones on IR and DL. Nearly 100 players who aren't even active can still voice their concerns - yes, those are the injured ones who are probably predisposed towards protecting their own! Plenty of managers and coaches, including former catchers, stand by the desire to not change the rules. Mike Scioscia is one who is adamant about it and instructs catchers on how to block the plate properly.

One of the most famous collisions in baseball involved Pete Rose bowling over Ray Fosse in an All Star game. Ray Fosse separated his shoulder in a fairly meaningless contest. He was never the same after that injury. He is on record as saying that collisions at the plate are and should remain part of baseball. His position has not changed and he was sought out after Posey went down. He maintains that changing the game is wrong.
Posey was hurt on a clean play. His spikes caused his ankle to be held in place while his body rolled back. Outlaw metal spikes?
They are paid to play and risk injury. They are entertainers.
