Come on, this is nothing new. Every once in a while you have a situation like this (Pete Rose/Ray Fosse, for one) that gets people really talking about it. And they should. It's one of those issues that people don't think about too much until someone really gets hurt, but it's not just bubbling up now because it was Buster Posey. I think it's one of those things that occurs to people when they see a catcher get laid out, but largely dismiss when they get back up. TT makes a great point, in that if you aren't allowed to blow up the other infielders, you shouldn't be able to blow up the catcher. Nor should catchers be allowed to interfere with runners. Neither catcher or runner are equipped for such high contact. And don't for a second dismiss the idea MLB would make that change. We're seeing rules in the NFL we would never have imagined even 10 years ago, largely to protect the investment of owners. Likewise, with franchise type players like Posey and Mauer cropping up at the position, it's not the least bit unthinkable to see them protected rather than just moved off the position. That wouldn't be the best motivation to make the change, but like the NFL, players are bigger, stronger and faster than ever in MLB, and it would be a rule change for the better. The only reason it has been tolerated for this long is because we love the violence of it, but someone is going to get really screwed up one of these days. Baseball isn't suited to high impact.
