Don't get me wrong, I love the running game. I like to see a team put the pressure on the defense.
However, there is an adage in baseball that the lower the league you are coaching in, the more your team should run. That is, Little Leaguers should run rampant, High school players less, college players even less, and, well, MLB is at the top of that list so they should run the least. And of course that's because of the defense. Usually even a "bad arm" in MLB would be pretty darn good anyplace else.
I don't take many issues with the planned running the Sox do. It's the crazy things that some players do on their own like trying to stretch a single off the wall into a double that bothers me. (Or trying to get from 2B to 3B on a ball that's hit in front of them! UGH!!)
