I told you I personally saw TWO guys get a broken wrist from collisions at first base while I was playing.That’s the thing. Where were all the injuries this is supposed to prevent? They’re not there. If we want to prevent injuries, let’s look at the pitchers. If you don’t have a couple of Tommy John’s on you staff every year, you’re the rare exception. Change si they pitch underhanded which puts much much less stress on you arm & shoulder. Ridiculous? Of course. But so is a green base to prevent a problem that never existed. And created problems of its own.
It's like running into the catcher. There are only 3 examples I can think of off the top of my head where a catcher got truly destroyed. Buster Posey, Ray Fosse, Buck Martinez all had career ending or career shortening collisions. So since it's only a handful of guys we should bring back being able knock out the catcher? Just because you don't know of the injuries doesn't make it a non- problem.
