Mike Rutsey. “Inside Baseball: Colliding views.” Toronto Sun. May 27th, 2011: “These days, though, hard, smash-mouth collisions at the plate are rare birds, close to extinction. The reason for this is the money involved as neither the runners nor the catchers are willing to crash into each other willy-nilly as perhaps they did in the past. There is too much on the line financially.”
Ricky Doyle. “Buster Posey’s Injury Unfortunate, But Home-Plate Collisions Still Have Place in Baseball.” NESN. May 29th, 2011: “to demand action to be taken as the direct result of the injury is a knee-jerk response, and one that is completely unnecessary. While they come with risk, home-plate collisions are rare occurrences in baseball, and injuries resulting from them are even rarer.”
