As they mention in the article towards the end, a common solution that's been presented is pushing the mound back a little. But, assuming that you want to keep all baseball diamonds from at least high school on up adhering to MLB regulations, think of the number of diamonds around the country that you'd have to alter to do that.
Also Fan Graphs had a piece a couple of weeks ago showing that there's been some evidence that something has changed with the baseballs and they're not traveling as far as in the past few years and home runs are down some. It's easy to imagine a scenario where something slightly changes again with how they manufacture the baseballs and home runs drop even further and you end up with an environment where there's still a ton of strikeouts and practically no scoring at all.
Anyway, based on the ideas he's already floated, I'm terrified Rob Manfred is going to try addressing this in the dumbest possible way. They've already changed the rules in the minors so that teams start with runners on 2nd if the games going into extras. And something leaked out a while back where Manfred floated an idea at some kind of rules committee meeting where teams would get to set their own batting order in the 9th inning of games. Which... just... what??
