The mental aspect of it, a true power hitter and a true contact hitter are seperated as much by their thought process as their mechanics, maybe even more so. I heard this from a coach and started asking questions of other coaches to get their feedback and for the most part all the opinions pretty much stayed on the same track.
A contact hitter will find the first avalabile pitch that is close enough to make solid contact, they are not as concerned at finding that perfect pitch as a a power hitter would be. And they seem to be more concerned about pitch counts than thier counterparts .
A power hitter seems to have little or no concern for the pitch count and will often let the first pitch slide by even if it is a called strike , because it is not ...their...... pitch, they have more of a tendency to go deeper in the count looking for that one certain pitch they can tattoo, not to mention taking particular pleasure in working the pitcher and making the coaches grow older with worry watching them. I just believe its the way they are hard wired.
But i think that Howard is correct in that a power hitter can go to the other side of things with the proper training, with the drills such as the attack mode it makes it easier for them to not be just one dimensional (sp)
