I pitched in college successfully for 4 years and IMO there are 4 kinds of pitching coaches (and I worked with Ray Burris who is the double A pitching coach with the tigers right now for 4 years during college on the side, met darren oliver, mike drumright, kenny rogers, etc):

1) The individualistic pitching coach – everyone is different so you cannot cookie cutter everyone however there are fundamentals that should exist for everyone such as equal and opposite, finger pressure, and plant foot mechanics. Basically, work with what you have, some pitchers are better throwing 3/4, others completely over the top.
2) The reinventer – Yeah so and so may be good however if totally revamped he would be much better. I dont like this top of coach.
3) The overly fundamental – Its all about making sure everyone has the exact same mechanics and refining ONLY these mechanics will make one a successful pitcher.
4) The hands off approach – just work hard and everything else will take care of itself. Run a lot, do the right exercises, throw a lot. Mechanics dont matter that much, just repeat them.

My question where would each of these coaches fall if you were to classify them into one of the categories? I know Ray was very individualistic. It seemed to me that Mark Conner was definitely overly fundamental which I think hurts young hurlers like volquez and would have hurt pitchers like feliz who looser arms. Just an opinion.
