Follow up: catchers blocking the plate

The columnists for MLB.com were very active in discussing these issues.

Terrence Moore urges baseball not to overreact. At one point he claims that runners are left with no other choice when the catcher blocks the plate, sarcastically asking if runners are supposed to try and slide around him. Let me emphasize this point again: plays at the plate are never that tidy. If the catcher is actually perfectly in position, you're out anyway. But he almost never is, so react to where the play has taken him and slide accordingly. He also cites Bobby Valentine and addresses the "macho" mentality of catchers. I certainly don't think any of my friends, family, or teammates would ever use that word to describe me. Ever.

Alden Gonzalez notes the continued specialization of catchers, ultimately wondering about the extinction of a true "two way" catcher. Unless there's a rule change about collisions, of course.

Mike Bauman points out how impossible it would be to enforce a rule that bans running over the catcher. His article emphasizes the fact that if these collisions are going to disappear, the change will come from the baserunners and not the league or the umpires.
