Completely disagree. Slow players will still be slow. Catchers that throw well will still fair well. 'Fuck Around and Find Out' will still apply to guys that lead off too far. What will stop: 90% of pickoff attempts, which were only being done to stall or 'keep the runner close'. Players will learn to steal bases again. It will make ABs more interesting, it will make pitchers work faster, it will reward teams that put the ball in play, and it will help kill the massive amount of 'downtime' that has crept into game times over the last 25 years and made what was once a snappy, enjoyable game to become like sitting through a movie that's an hour too long.
And the biggest reason why we should love it: the Gs are poised to exploit the shit out of it. Jose will go nuts. Kwan, Amed, Gimenez, and Brennan will see bumps in SBs. I think even Oscar gets into it. Straw will become a holy terror as a pinch runner. About the only issue could be Zunino if his arm doesn't rebound. It also allows the game to see a bump in scoring and action without adding steroids and juiced balls. And that alone should be looked on favorably by fans.
