For all the problems MLB has attempted to address, this one would seem to be the biggest, most complicated, and most significant threat to the future of the game. Offense being terrible and continuing to trend downward is going to eventually affect the bottom line. Clearly banning the shift wasn't the answer, so what other levers can they possibly pull? There is the oft-mentioned but never seriously considered lowering of the mound, but I'm not sure how much that actually accomplishes. Other than that, I have no idea.
