Problem with hook slding is that it essentially lets the catcher and umpire off the hook for obstruction. You can argue that the player was going to hook slide anyway so the catcher blocking the plate didn't cause the runner to change course so no obstruction. Reality is that a hook slide to avoid a tag when catcher is set up or drawn by the throw to the 1B side is a smart play. A hook slide to avoid a collision with a catcher camped on the plate without the ball is a sign that
#1 Obstruction isn't being called enough and it's enough of an epidemic that more coaches than not teach their catchers to block the plate.
#2 Way too many baseball coaches/umpires are involved in softball. I get the impression that in the areas where the sports differ there are many who want them treated the same in order to improve the sport which is funny because there are some on the baseball side who seem to be arguing that maybe taking out the catcher at home plate and the SS on a double play doesn't 100% need to be part of the sport. I know the Twins have a SS that came over from Japan that didn't understand our rule intrepetations for MLB quite clearly enough (probably a language barrier
) and had his leg snapped when a runner took him out to stop a double play. He didn't get that it's an important part of the sport to not only interfere with a fielder but cause them grave bodily harm when possible.
I guess it's that kind of dualism that makes America great, kind of like nearly making it illegal to smoke cigarrettes while simultaneously trying to legalize marijuana.
