Agree with you wholeheartedly there GAC! Lay down a bunt, hit to the right side, hit the cutoff man....these are things that you're supposed to know by the time you get to the bigs!
Maybe because players don't get the fundamental coaching early on, maybe because they are rushed through the minors, maybe because (as you mentioned) it isn't glamorous, a lot of guys that wear big league unis don't seem to know how to do these things! And, if your stratagey relies on someone being able to do the basics but they don't, you're in trouble. And, trying to teach someone to do these things when they are in the majors but didn't learn them in 15 years of baseball at other levels is a very big uphill climb.
