Even if u put it down, the point of the tag is to have it touch him before he hits the bag, or overruns or whatever. Otherwise why would people try to barrel thru the catcher? Because even if he tags u, u could knock the ball loose. I understand that they do it all the time, and obviously they just ASSUMED they would be out, but why play the sport if that sorta thing is gonna be based on assumptions? or even lay a tag down?
