To be fair, thinking in general on concussions has changed dramatically in just the past couple of years. I think comparisons with past standards and expectations are pretty much out the window at this point. That's why MLB instituted a new 7-day DL for just these types of injuries. You're going to find all stakeholders in the game (owners, athletes, FO types, agents, medical staffs, etc) being much more cautious than in the past. It makes the question of should he move to reduce the chance of future concussions very legitimate in my mind. And I think the fact that catchers Iand umpires) are so prone to this type of injury is something MLB is going to have to address sooner rather than later, just as the NFL is being forced to address it.
