Major League Baseball should take down all the protective netting around the field that is meant to protect fans from foul balls. WIthout fans, it's pointless, plus if a player hits a foul ball, he could decapitate one of the cardboard fans and that would be amazing.

One of the main problems with fan-less Major League Baseball is announcers filling time between pitches. You let a Mookie Betts foul ball take the head off a Larry King cardboard cutout and there is no more awkward silence.
